Adrian was relieved that Bruce said he'd help him and he said "Thanks Doctor Banner. I really appreciate the help."
The man knew how harrowing being on the run was. As an assassin it only got worse for Adrian because terror organizations don't like having their leaders lobotomized with a bullet. He sympathized with Bruce being worried about still being hunted because Adrian himself was still paranoid about HYDRA coming for him and paranoia was an understatement. Adrian was often scared out of his mind that he'd be captured again. He was still plagued with nightmares and flashbacks from the year he spent as a prisoner and lab rat for HYDRA.
A flashback of Red Skull killing his unit and taking him down in a single hit suddenly came rushing back to him and he had the expected lapse of awareness but it looked like his mind simply wandered for a moment.
"Yeah, I know about it. Did anyone tell you about my old job?" Adrian assumed the Avengers file on him would have been showed to the whole team. SHIELD had employed him as an assassin and he'd made entire terror cells disappear. He used those skills now to help people and was a very effective countermeasure against people with similar skill sets to his own.
"No problem Doctor. Just a heads up I tend to swear when I get pricked with needles."
