Wow, sorry to hear about what happened . I was just thinking the same as alex; I thought you two were just getting bored with us .
Seriously though, I'm really glad that he lived through it and the fact that he's staying with you two and getting better it a very good sign. Just so we can get an idea, could you tell us the relationship (parent/sibling/friend) this person has with you?
If he is willing to come along to convention, I for one would love to show him a fun time to get his spirits up.
