I don't have a problem with you utilising my ideas. After all, I'd feel honoured if they actually helped you in some way. Also to note, I do have some pretty interesting ideas on what I want to happen to my character, but those surprises are best left silent to see if the opportune moment arises. More than welcome to use those or re-imagine them to your own liking.

Edit: and I only just realised it's 2:40am, so I should get some sleep instead of being here. :P
