After the Liberty Island incident, P. Xavier wants to know the nature of Logan and Rogue relationship so he asks about it to the team. The answers are interesting;

They’re clearly soul mates. It’s just a matter of time till they get married, chica! - Jubilee

He's a pervert. Don't you see the way he looks at her? Can't believe you keep letting him stay at the mansion. - Scott Summers

Why do you make such a big deal? He’s just being protective, that's all. Oh, come on! She's just an average teenage girl with a silly crush on him. Trust me, I know he chases another kind of woman - Jean Gray

It looks like he wants to eat her - Bobby Drake

They share a special bond. Personally, I think it's cute. - Ororo

Now that you mention it, they hang a lot. I think they're best friends, da. - Colossus

I don't know, but If I ever know that Logan got to screw an untouchable 16 years old girl he will become my hero! - Pyro

Uh, why do you ask?...he's my friend - Rogue

Are you fucking kidding me? Get outta my sight before I gut you! - Logan
