No one. No, seriously, sometimes I think he'd be better off alone. At least for a little while. Because he clearly doesn't know what to do with Quinn & Rachel (just like in 2x21, when he told Quinn he wants to break up with her and then when she cries, he's like he wants her to forget what he detto and wants to stay with her anyway ...)
I would say Rachel but both Rachel and Quinn have hurt Finn but then again he can be a bit of a winger sometimes but definitely Rachel cause she has always liked him not just cause he was the quarterback and popular.
i reckon finn shouldn't data anyone hes had hes up and downs with both quinn and racheal and his life hasn't changed a bit dating them so no on but if i had to choose i'd choose mercedes coz shes never had a boyfriend and has never felt loved before. Until she meets sam of course
Quinn, she actually knows him, she understands him, she can handle him best, they actually have an awful lot in common and want similar things and they were each others first loves so it doesn't matter how "in love" they are with other people, they'll allways have that special connection.
