out of character:
Backtagging: Yes. Yes. Forever yes.
Threadhopping: Go crazy. 83
Fourthwalling: I prefer to keep it minimal, so ask before doing so.
Offensive subjects: Pretty much anything goes.
Hugging this character: Go right ahead. Even if he won't be very happy about it, deep down he probably really needs a hug.
Kissing this character: If you really want to... (yes)
Flirting with this character:
Why would you ever-Yes. Keep in mind though that Stannis will probably have no idea wtf you're doing.
Fighting with this character: Most definitely. He's not exactly the most agreeable guy.
Injuring this character: Nothing too serious, but let me know what you have in mind.
Killing this character: It depends on the situation.
Using telepathy/mind reading abilities on this character: Be sure to let me know, but otherwise most definitely.
On Spoilers: As Stannis is from A Dance with Dragons (in Asgard), be sure to let me know 1) if you do not want spoilers or 2) you want me to avoid tagging your character entirely. In general, there will be spoilers up to the end of A Storm of Swords.
On Tagging: I am aware that A Song of Ice and Fire is not to everyone's taste. If you'd like me to avoid tagging you with Stannis, please let me know.
