As for the likelihood, when he gets back his memories are going to be a jumbled mess due to some severe trauma and the like. Only thing that'll be clear to him is his daughters and his desire to protect and care for them.
As well, he's not going to be super interested in past conflict and pretty much will just let whatever issues he had with Confutatis go because literally all he'd care about is his daughters. He's also been attracted to her before and I think if she caught him in the right moment that attraction would spark up again.
