Commentary for Kiddushin 124:4

If R. Yohanan agrees with R. Oshaia in the earlier case, then maybe we would have our answer to this other case, where a man tries to betroth a woman now and again after he divorces her, all within one act of betrothal. R. Oshaia did not know the answer to this, but it would seem that since he can’t marry her against her will after he divorces her, even if she consents now, the second kiddushin would not be valid.
The Talmud answers that maybe in this case her consent could carry over to the second kiddushin. Thus this question still remains.
