Fortunately, it would not happen again.
"Someone was following you, but he didn't do anything to you. So, I think you should know that this person was just making sure that something happened. As expected, he probably wanted you to have sex with Sarah. Once you've slept with Sarah, that would be the end of your and Monica's relationship."
Finn agreed with Jeanne's logic.
"I think we both know who this person is."
Yes. They both knew that Michael had ulterior motives.
However, Monica did not believe it.
Hence, Monica would be hurt by Michael in the end, or Michael would give up a lot for Monica, but it was not his problem to consider anymore.
That was Monica's choice.
"You don't care if Monica was deceived, right?" Jeanne did not get Finn's reply, so she asked him.
"That was her choice, and she has to bear the consequences."
Jeanne did not try to persuade him further because Finn was right.
