Bernice is a special case, in Jamie's opinion. He feels she can get away with quite a bit, given her and Braxiatel's rather unique relationship. However, Jamie does understand the concept of taking a name for yourself - he's quite aware that the Doctor has done the same at some point in his past, even if he's unclear on what the Doctor's real name actually is.

So he nods, and says, "Well, then. I'll just have to keep that in mind." It likely will mean that Jamie falls into the habit of calling Brax 'Irving' as well. It does suit the Time Lord, in an odd sort of way.

The movement causes another stray bit of straw to float off, and Jamie notices it out of the corner of his eye. "I suppose I should go back to the cell," he says reluctantly. "I know they won't know I'm gone while I'm here, but I've got to figure a way out of there somehow, aye?"

He had been hoping coming here would help him think. All it seems to have done is provide a distraction, however. Not a bad thing in and of itself, but it doesn't help his current situation. At least he's got a book now, although he really can't think of much to do with it besides possibly hit a guard in the face with it as a distraction.

Given the look he's giving the book right at the moment, he may very well be planning on doing just that.
