because this is clearly a mistake in the script and it's Ellie who says that line.
If you look at the exchange it is clear from the sense and the back and forth that is Ellie speaking:
Python:
e "If I tell him, everyone will know!"
s "Well, there's your next proof that he's not the right one for you! Cause if he was, you would fully trust him not to tell anyone!"
s "Well, I could also just ask him to have gentle sex with me."
s "Oh, please. The way I met Logan, it's like asking a bull at a bullfight to be more gentle to you!"
s "Ellie, it's really important! You must talk to him about it beforehand!"
If it has to be Logan, I don't see Sophia sacrificing herself to save her daughter, it's a bit unrealistic and a bit out of character.
Unless there is another blackmail involved, like "I'll leave your daughter alone only if you sleep with me", à la A Mother's Love. But I don't think so.
In case it is Logan, I rather see him trying to seduce Sophia during some event, another night at the club or the bachelorette party for example (they might meet randomly), where things could be already a little bit of control. Something in that spirit but I agree with
hzjujk and don't see Sophia playing the martyr just to save Ellie's virginity.
