On live feed now Dexter saying that he is dyslexic and think he mentioned having dyspraxia too. Said he can't add things together or even write his own name without it looking illegible. Said he has often been called stupid and told he didn't have the smarts to do what he wanted.
Callum is apparently an accountant, excellent at maths and Dexter reckons that Callum is extremely intelligent academically. He said he always wishes he had the same type of analytical intelligence that Callum has and feels that Callum is able to predict things in the house that Dexter can't see yet.

Although he tried to say that he thinks he is still more 'street smart' is there a little bit of jealousy or insecurity there on Dexter's part because of the 'on paper' achievements of Callum?

Callum doesn't buy Dexter being so humble and says that he knows Dexter is only trying to portray a certain humble image to the public but that he respects that it is Dexter doing what he needs to do to succeed with the public.

I think Callum mainly dislikes Dexter because of the time he spends with Charlie, but is jealousy of intelligence the reason Dexter dislikes Callum so much?
