Re: "You ready for another Bout?"- The Thor/Chris Hemsworth Thread
The only psychological change I'd want is for him to have more of a "yeah whatever Loki, you do that again and I'm going to smash you straight back to jail" type attitude.
The rest of Thor's behaviour etc should be based on the events of TDW.
I especially don't want the actual battle in Avengers to have any psychological effect on him - It's so far from his 'first rodeo' *cough* that he's hopefully 'used to it' a bit.
Does odd things at random times.
