So I have a dilemma and I'm really not sure how to go from here. I basically did something very out of character because I don't do good RP on the fly; I had a plan, forgot step one and things went downhill from there.
We started the session after having found the TotallyNotViking prisoner beneath Brinewall. Our social character had just failed to talk to her and was in the process of walking out with her weapons. Step one of my plan was to stop him or just take the weapons so he wouldn't leave with them. I forgot.
My character is a Skald (Bard/Barbarian hybrid class) and a gnoll. He's fairly kind-hearted since he was raised by Koya (cleric of Desna). He tried talking with her by expressing that the guy walking off with weapons had an oath of protection to keep and the like, this didn't really go over well. I didn't take Diplomacy so I naturally failed the DC25 roll to try to get her to listen.
So I somehow, after forgetting to stop him walking off with the weapons, decided the reasonable thing to do was to walk off with her armor. Leaving her without anything and telling her she may as well not have them since she was going to starve to death.
This is naturally very very very out of character (and is in character for a character of mine in a very different game). My Skald got into an argument with the face of the group about this and stormed back into the room and through the other side, tossing her armor in front of her cell. Which now had been broken out of. So we have an angry TotallyNotViking likely to come after us.
My main issue is that basically everything I did was completely out of character for my Skald. I thought of possible development, but it wouldn't make sense to have done all that. Naturally it's very much too late to take it back.
I kind of feel like I've damaged the character concept pretty badly and I'm not sure what to do now. We're on break until our next session since we finished at Brinewall, but I still can't think of a way for it to make sense for the character. (For the player it was because I emulated the wrong character).
