Ive finally figured out who he reminds me of
 

Sam: BB7

I cant believe I never realised! They both are very needy, always trying to please and allways trying to be happy and are just socially awkward.

I felt sorry for Sam in BB7 the same as I do Christopher now but I simply cant stand him as a housemate like I couldn't with Sam they just are not good housemate material.

Can't see it myself. Christopher is more likeable.
