This, in a sense, would be a rather extraordinary and interesting ending. But this does not exclude the possibility that Claire and MC could have a relationship, on the contrary, it would be very logical.
As an old man, a father and a grandfather... one who has a fair amount of experience with male/female relationships... let me see about clearing this up for you, my friend...
Claire does NOT yet find her little brother sexually attractive. He is far too soft and squishy to be the kind of man she likes. This is one of the reasons that she is trying so hard to train him. She loves him and wants to see him stand on his own two feet as a man. She still sees MC as a boy... because HE IS!!! He has a lot of growing up to do in a big fucking hurry IMHO. Claire is an alpha who goes for other alphas. So, it will take a long time to whip his soy boy ass into shape! He needs to sharpen both his mind and body. Claire is trying... she really is trying!!! Meanwhile, MC does get the occasional pity fuck from Jill because... Jill just wants the dick!
Ellie is in that same camp as Claire. She sees MC as soft and squishy, not yet a man. Ellie even tells him so in public saying that she is more of a man than he, even Jill agrees from behind the bar. However, Ellie still finds herself turned on by MC so that will likely happen long before anything with Claire. And Jill... well, Jill just wants the dick. She works many long hours and doesn't have time to pursue a relationship which is why we catch her with Nico at the gym, a hot tryst of convenience, the same goes for Jill having sex with MC...
The same thing applies to MC always running off to meet up with Eve and Syd. Those two essentially OWN him. Syd never seems to have much time for MC and Eve always has the need to sneak around like she is embarrassed of him. Both situations are bullshit. I have played along thus far as I find them both adorable but I'm getting the feeling that MC is just being used, needs to stand up for himself and drop the little lost fucking puppy routine.
Thus far, the only potential "LI" where we have had the opportunity to assert ourselves was with Jane trying to pry MC away from her mother to spare her little mama's boy brother his little feelings being hurt. Fuck him and fuck Jane! Their mom is able to choose who she wants to fuck and if she wants to keep fucking me, I will in turn keep fucking her! She's not as hot as Emma but she certainly is a hottie! My thought through that entire conversation was, "Why the fuck are you talking to me about this? You should be talking to your mother!" So, I flat turned the bitch down.
The other situation where MC FINALLY was able to assert himself was with Natasha... I felt a bit like Smeagol in that scenario... "Leave now and never come back! Leave now and never come back! Leave now and never come back!"
Hahaha
Smeagol is free!!! Hahaha
TBH, That was the most satisfying scene in the entire game thus far, for me, getting that sick, twisted, control freak, stalker bitch off of our backs. HATE that kind of shit with a grand passion. Natasha was doing the same thing to MC as Emma's sexually predatory co-workers are doing to her where she works. If I were in Emma's position I would carry around a small recorder to capture all of the lewd comments, making sure to mention their names on the recording for clarity in the courtroom and sue every last one of those mother fuckers!!! Getting them all busted would trim out all of the fat in the middle management tier at that company and Emma would finally be able to implement her cost savings, profit earning strategies... Go Mom!!! Yes, I do love Emma and want to see her succeed.
Anyway... I set out to say a few lines and ran on half a page... Hope that gives you a bit of insight as to the nature of the relationships in this game.
Adventure ever on my friend, Phat
