It is an immediate regret that hits him when he sees the almost calculated look from Jack. Of course, from a doctor's point of view a comment like that is not taken as a fun little quirk. It doesn't give you the charming points you might get from someone else who has no idea how trauma looks on a person. Silver might carry his with a carefree recklessness, but it doesn't make him immune to pain, so he looks away. Now isn't that just great, he thinks, this habit of his to allow his words to spew out before he's had the time to filter them.
He doesn't dwell on that for too long, however, for when he next looks back at Jack, he can't help the light laughter that follows. Closer to a gentle chuckle than anything. When did he last spend an entire evening watching TV? Probably high and fighting to keep his thoughts chill instead of drowning him in terrors that always came at the worst possible time. No, there will be no TV. Nothing of that sort, for the most dangerous thing is for him to be alone with his own thoughts.
"Ah, you know, I really should, shouldn't I? Just, I have a double tonight. Someone called in sick and all that. But, I could also lie and say that I will definitely have a relaxing evening in front of the TV. All depending on what you deem most truthful"
A playful smirk, one that makes it very obvious that he will not have a relaxing evening at all, but at the same time with a look that shows that he is grateful. It isn't necessary for Jack to give advice to a stranger like himself, but it is also nice to know that even if it might be simply fleeting, there is something genuine to that concern.
"I'm fine. Really. It's just a scratch and some bruises, but thanks"
