Will you be able to use Devin every once in a while? I ask because when he wakes up I intend to have my character interact with him and I don't want to control him TOO much to involve getting him out of character in the way you'd present him.
I don't mind including my character in the story but short of someone stumbling on him or something would you mind leaving him unconscious for at least a day in-world? Just to give myself a little time.
If you've got another idea or something feel free to run with it though.
