Backtagging: I have nothing against this, just give me a note if you want to continue super-old thread or something. :>
Threadjacking: Go ahead. Except the thread has been marked private or something alike to it, obviously.
Offensive subjects: Naw, I'm cool almost with anything that you can toss at me!
Fourthwalling: ...Well, it depends. Ask me first?
Fighting/Injuring etc.: By all means, hit him all you want. Gilbert is actually bit of a masochist so there is a chance for him to actually like it. But any serious injuries and damage needs to be plotted.
Death: This can be arranged. But again, let's plot first.
Hugging/Kissing: Feel free to try. His reaction will definitely depend on his mood rather than who your character is. :/
Sex: Uh well, yes. Gilbert is promiscuous and sex is quite important part of his life.
Rape: Gilbert is such a special little cookie in the jar that he doesn't actually always mind this, and it's sometimes difficult to tell if it's a rape or not.
Becoming an addict: It would be canon for Gilbert to get hooked up on drugs. But still, I would rather avoid this. :/
Mindreading etc.: Go ahead. But I don't think you want to. His mind is pretty twisted and dark.
Anything else?: If you have questions or something ask away :>
Also! Gilbert's canon contains a good amount of rather triggery subjects like incest, pedophilia, prostitution, rape (and other sexual abuse), drug abuse etc.. And since Gilbert is one of the main characters he is involved with most of those things. If these subjects makes you feel uncomfortable or something inform me and I will avoid bringing them up while Gilbert is interacting with your character!
Oh, and like I mentioned before this kid is very promiscuous and can be slutty too (in canon he has pretty much seduced almost entire student-body). So! if your character is a man there is a chance that he might try to seduce him (and play mind games later but pssh, details). This really depends on his moods, though, and if there is something he could gain from doing so. Though he is sort of addicted to sex and he can get rather desperate and suicidal sometimes. If this makes you feel very much "ewwwwwww dnw" or "eff yes 8D" hit me! ;>
Dormant ability:
While being at Siren's Port Gilbert posses a dormant ability! And what is this ability, you ask? Well, it's like he has love potion on his lips (think of Poison Ivy);
Gilbert can make people more to him by kissing them. People he kisses might even end up falling in love with him, feeling lust for him, or even obsessing over him.
Originally, I didn't plan to have this power to be activated for any time soon. But still just to be sure, if you want to have your character affected by this ability, or to be left out of this completely, please tell me. :>
QUESTIONS? CONCERNS? Hit me. I will also keep this updated if I feel like that there is need for it.
