There is the role command that you can use in game to write a role. Writing roles are optional, but they do help the immortals understand your roleplaying more readily(especially if its an atypical role idea). Even if you don't have a written role, you need to stay in character.

As far as asking, you can ask if your character would do so, but don't expect answers. Be wary though, if you ask that question, it can come off as whiny(you have to be very careful on saying it). I have had a character that always wondered why anyone would harm such a beautiful creature such as he(he wasn't exactly modest). Some people mistook his simple questions as whining. Basically, you can ask, just be careful about it.
