Jackson caught the purse with practiced ease, giving it a toss to try and get a feel for what was inside, before slipping it to a pocket. He watched curiously as she procured a note from the dead man's body, and sidled up to read it over her shoulder [which wasn't all that hard, considering he was taller than her by a few inches]. He quietly started when he read the name 'Benedict,' not expecting to see the name again.

So when she asked and dismissed his name, his shoulders relaxed a tiny bit from her lack of inquiry. It would do no good to try and hunt his former mentor, Benedict Cumberbatch- a most inquisitive and eccentric man, whom they would not do well to cross, regardless if he tells people where to find him. That, and he was pretty sure he also had magic. 

And so it was quite easy to simply say, "Aye, we shall. Might as well purchase some good horses for once, on the good Captain's purse, of course."
