Troy/Nell/Maura/Others
Troy wasn't sure why he was there. Not the right blood type, not the nurse type, and he knew that because those weeks with April had been the worse thing evah. It wasn't that he didn't like April like some of the others, but that he didn't like bodily fluids that didn't involve sex or cool video games, because then blood was awesome.
So yeah, he had no idea, or at least he didn't until he and Nell entered that room and Maura was taking about taking out the bullet without surgery. That he could do, thanks to a long conversation with Callen that led to lots of training and anatomy books.
"Callen made me do this at the ranch," he told Maura. "We tried different places, avoiding major blood vessels. If you show me the x-ray and tell me what I need to avoid, I should be able to do it with minimal impact to the body... I mean to Travis." This was so much easier when it was all theoretical and there was a man looking like death on the floor of a room. "Do you want me to -" He waved toward the kitchen counter they used to prepare food. "Maybe something to put on the sink for his legs, and garbage bags, because... we kind of cook there." Food and blood were not a nice combination, unless they were having a thick steak covered in barbecue sauce.
