something about Callum

he is hiding something ,a sadness for sure.

He does come across as creepy Baz.

In my trying to understand Callum I do believe he lied on his vt to make him sound more interesting to get into BB. From observing him in the house I've sensed he's very intense, and through his facial expressions in discussion with other hm's he also has a nervy disposition but covers it up with over emphasising his memory of convo's he took part in. I also feel he's hidden for a while a side of him that has very strong feelings that could erupt in anger and frustration given the right circumstance. Of all the hm's his personality/character is the most psychologically interesting to me - the others seem pretty easy to read, but yes I could be wrong lol.

I've said from the start that Callum comes across as being a lot more skilled in PUA techniques than the guy who supposedly teaches them (Dexter). Now by that I don't necessarily mean that he's a "Pick-Up Artist", but he does display a very "controlled" personality. Whether that's so as to try to influence and manipulate people (as a PUA would do), or whether it's - as others have suggested - a mask to hide certain aspects of his personality, I still don't know...
