281 S.E.2d 438 (1981)
STATE of North Carolina
v.
Herman CHARLES.
No. 8114SC97.
Court of Appeals of North Carolina.
September 1, 1981.
*440 Atty. Gen., Rufus L. Edmisten by Asst. Atty. Gen., Grayson G. Kelley, Raleigh, for State.
B. Frank Bullock, Durham, for defendant-appellant.
WELLS, Judge.
In his first assignment of error, defendant contends that the trial court erred in denying his motion to dismiss the charges against him by reason of the failure of the State to begin his trial within 120 days of his arrest. In his speedy trial motion, filed and served on the State on 14 December 1979, defendant alleged that he was charged with murder and arrested on or about 14 August 1979, that he had not been indicted, that he had not been tried, that no part of the delay of his trial was attributable to defendant, and that the State, without a valid reason, had failed to accord defendant a speedy trial. Defendant's motion did not come on for hearing until 10 April 1980. In the meantime, defendant was indicted for second degree murder on 8 January 1980. At the hearing before the Honorable James H. Pou Bailey on 10 April 1980, the trial court took judicial notice of the foregoing sequence of events and that defendant's file indicated no reason for the delay between the arrest and the indictment. *441 The State argued to the trial court that because there had been no showing by defendant that his trial was not "granted" within 120 days of the indictment, defendant's motion should be denied. The State made no effort to explain or justify the delay of trial beyond 120 days of defendant's arrest. Judge Bailey denied defendant's motion. We find no error in Judge Bailey's ruling.
G.S. 15A-701(a1) provides as follows:
Notwithstanding the provisions of G.S. 15A-701(a) the trial of a defendant charged with a criminal offense who is arrested, served with criminal process, waives an indictment or is indicted, on or after October 1, 1978, and before October 1, 1980, shall begin within the time limits specified below:
(1) Within 120 days from the date the defendant is arrested, served with criminal process, waives an indictment, or is indicted, whichever occurs last.
G.S. 15A-703, in pertinent part, provides:
If a defendant is not brought to trial within the time limits required by G.S. 15A-701 ..., the charge shall be dismissed on motion of the defendant.
In felony cases, there are a number of events which may start the running of the 120 day period provided for in G.S. 15A-701(a1)(1). See Chapter 15A, Article 17, Criminal Process. The General Assembly revised the Speedy Trial Act in the 1977 Session. See Chapter 787 of the 1977 Session Laws. The original version of the Bill which contained the revisal, H.B. 718, filed 4 April 1977, contained a provision that the first of the events enumerated in G.S. 15A-701(a1)(1) would start the running of the 120 day period. The original draft was the one recommended by the Legislative Research Commission in its Report to the 1977 General Assembly on Speedy Trials. The Bill was amended in Committee to provide that it would be the last, not the first, occurring of the events enumerated in G.S. 15A-701(a1)(1) which would measure the 120 days, and it was the Committee revisal which was enacted.
Recognizing that under the provisions of Chapter 15A, Article 17, Criminal Process, arrest may precede indictment or indictment may precede arrest, we believe that G.S. 15A-701(a1)(1), as finally enacted, reflects the clear intent of the General Assembly that it is the last occurring of these events which will trigger the running of the 120 day waiting period.[1] In the case now before us, the last occurring event in the criminal process chain was the return of the Bill of Indictment by the Grand Jury on 8 January 1980. Defendant's trial began on 10 April 1980, well within 120 days of the return of the indictment against him. Compare State v. Young, 302 N.C. 385, 388, 275 S.E.2d 429, 432 (1981). This assignment is overruled.
Defendant's next assignment of error concerns the testimony of Damita Jo Lemon. Prior to recess, Lemon had testified that after hearing the first shot, she heard the voices of Robinson and defendant. Although she was not specific about what was said, Lemon did remember that defendant's voice used profanity. After the recess, Lemon testified on direct examination that after the first shot she heard Robinson say, "man, you got me," and then heard defendant say "m____ f____, die." Defendant contends that the trial judge erred by permitting the State to impeach its own witness. The State, however, was clearly not seeking to introduce prior inconsistent statements or to impeach Lemon's credibility and therefore this assignment of error is without merit. Compare, State v. Berry, 295 N.C. 534, 537-38, 246 S.E.2d 758, 760-61 (1978).
Defendant also assigns error to the admission over objection of Lemon's statement on re-direct that when defendant returned to the house after the shooting, defendant told the occupants that if the police asked who shot first, they should say Freddie *442 Robinson. Lemon did not testify to this on direct examination, and defendant contends that the State was improperly allowed to produce new evidence on re-direct examination. During cross-examination, while Lemon was in the process of relating the statements defendant made when he entered Lemon's house after the shooting, counsel for defendant interrupted her in the middle of a sentence and requested that she confine her answer to what defendant said about calling an ambulance. On re-direct, counsel for the State asked her to complete her recollection of what defendant said when he entered the house. She then stated that after asking those present to call an ambulance, defendant said that if the police asked who shot first, "say that Freddie shot at him." It was within the discretion of the trial judge to allow the witness on re-direct to clarify testimony elicited on cross-examination. See 1 Stansbury's N.C. Evidence § 36, at 109 (Brandis rev. 1973). This assignment of error is overruled.
Defendant next assigns error to the admission of the corroborative testimony of Detective Clarence Gooch. Gooch's testimony concerned conversations he had with Willie Vine, Jr., held shortly after 14 August 1979 pursuant to Gooch's investigation of the shooting. Although for the most part consistent, what Vine told Gooch differed in some respects from Vine's testimony on direct examination, e.g. Vine told Gooch he heard four rather than two shots, and Vine told Gooch that after the shots he heard defendant say "I got you," and heard Robinson say, "Oh, you got me." "[I]f the testimony offered in corroboration is generally consistent with the witness's testimony, slight variations will not render it inadmissible. Such variations affect only the credibility of the evidence which is always for the jury." State v. Warren, 289 N.C. 551, 557, 223 S.E.2d 317, 321 (1976). The variations were slight in this case and defendant has failed to demonstrate any prejudicial error and this assignment of error is overruled.
Defendant next asserts that the trial judge improperly expressed an opinion during the instructions to the jury. G.S. 15A-1232. In summarizing the testimony of Lemon, the trial judge stated: "She also reported that she heard some vulgarity that I see no need to repeat for you. I didn't enjoy hearing the vulgarity under any circumstances, but these witnesses were telling you what they say they heard." Considered in the context in which they were made, these statements by the trial judge could not reasonably be considered as an expression of opinion on the evidence in the trial. The trial judge merely declined to repeat the profanity and then explained his omission. This assignment is overruled.
Defendant's final assignment of error concerns the trial judge's denials of defendant's motions to set aside the verdict as being contrary to the evidence, for a new trial, and for a mistrial. A motion to set aside the verdict as being against the weight of the evidence is addressed to the discretion of the trial court, and is not reviewable on appeal in the absence of abuse of discretion. There was more than sufficient evidence to take the case against defendant to the jury; hence, no abuse of discretion has been shown. State v. Hamm, 299 N.C. 519, 523, 263 S.E.2d 556, 559 (1980). Defendant's motions for a new trial and for a mistrial are not supported by any showing of prejudicial error in the trial. These assignments of error are overruled.
Defendant received a trial free from prejudicial error.
No Error.

NOTES
[1]  Our holding recognizes, of course, that there are other events in the chain of criminal process in felony cases which may control.
