I think Liam made it very clear to Amy that he wasn't interested- and that was after a purely sexual 1st night encounter. Brian has liked Amanda for weeks, and would love a RELATIONSHIP with her, not just sex, like Liam. Amanda is very young and is having problems being honest to Brian. she doesn't fancy him but has not made that clear, so he is hanging around in no-man's land, feeling bad about it. Also I think nobody felt sorry for Amy cos she was clearly such a slapper! Amanda is sweet and nice.
