Imprinted Roleplay
Rationalization and Self-Awareness.
Character who have been imprinted are never aware that the desires or feelings they now have are alien, or because of any sort of mind control. They will always rationalize why they want or feel something, and why it stopped. They do not act in a way that is robotic or at all out of accord with their character, it should be extremely difficult for another person, even if that person knows them very very well, to know they've been affected by something. The new desires and feelings are integrated into their current personality. They can rationalize away being mind controlled even against massive evidence. They feel entirely certain that they are still them and all their desires and feelings are their own.
Obedience
Level three imprints are always obeyed, even if the imprint was to strangle your grandmother with her own intestines you would follow it.
Level One imprints constitute a strong but normal desire to do something. If someone imprints you to want to get up and do a chicken dance you really want to get up and do a chicken dance, you're sure it'll make people laugh and they'll like you etc. You may not follow this compulsion however if for instance you have crippling shyness. Or it would interfere with an unusually strong desire or inhibition. For instance you wouldn't likely murder someone because of a level one imprint, unless your character was fairly blaise about murder. Your character also probably wouldn't stop defending themselves or others from serious injury or death, or stop having sex midway through to follow it. Anytime you have a very strong inhibition that would prevent you from following the imprint, or it would conflict with another desire of yours that is beyond that of a normal desire it's acceptable to not follow it.
Level Two imprints constitute an extremely powerful desire to do something, or equivilant feeling. Only the most potent inhibitions or conflicting desires can stop you following this. This generally has to be life or death stuff. Not following an imprint of this level is like jumping off a five story building, if your inhibitions or competing desires are strong enough that you'll risk possible death and certain severe injury to follow them, then it's feasible you won't follow the imprint.
Tips
-If you're on the fence if you should follow an imprint or not, follow it.
-If you think an inhibition or competing desire would stop you following an imprint, ask yourself if that inhibition or competing desire has come out clearly in your roleplay previously. If it hasn't you're on pretty sketchy ground.
-If you decide not to follow an imprint, it's usually a good idea to at least show through your roleplay that you're thinking about following it or tempted to follow it.
-Being 'strong willed' or anything similar is a completely invalid reason for not following an imprint.
-Having been imprinted several times before, or being able to do mind control yourself is not a valid reason to be aware of mind control or be more resistant to it.
-If an imprint is something that your character normally wants to do and sometimes does it's not unreasonable to have additional resistance to it.
