Greenseer-Queen Bran wrote: Jon became one of Tyrion's closest friends. In the books they became as close as brothers during their journey to the wall.

Theon did treat Jon bad during childhood. Then he did betray the brother they loved both. Theon thinks that he deserves to be executed by Jon.

Jon and Tyrion have not seen each other since the First Season, so they've been apart for at least three years. And considering that Jon almost deserted the Night's Watch to fight for Robb Stark, and Tyrion Lannister was on the other side of that conflict; they may not have been so chummy with each other.

Funnily enough, Theon still refused to come to Castle Black with Sansa. He went to the Iron Islands instead. I fail to see what debt Theon owes to him.
