OUT OF CHARACTER
Backtagging
I'm all up for this, after all everyone gets busy from time to time.
Threadjacking/threadhopping
If it's in a random post, then go right ahead. But if it's one that's private then no. For the rest I would need to be asked.
Fourthwalling
Only with permission.

ACTION
Fighting
Why would you want to? Unless it's for sword practice or a very good reason then no.
Injuries
He's just a boy, every teenager gets injuries.
Killing
Please ask. I'm usually up for it if the reasoning is good, or the plot is fun.
Telepathy/mind-reading
Permission as to what would be nice.

RELATIONS
Hugging
Go right ahead, if your a girl he would love that. If your a guy... not so much.
Flirting

Do it and he might do it right back...
Kissing and/or other intimate actions
Okay, this would properly weird him out. Unless of course he's in a relationship then that's okay, but yeah.
Anything else you'd like to make known? N/A at the moment
