Frazer leaving marks on him as something of a claim.

[avali]

Something he can pass off as a nick from his last job, keeping her settled because it means she's left her mark on him long after the drugs wear off.

And Talbot knows about it; he's not blind. She's more transparent than she thinks given that they spend nearly every day in one another's company-- but it seems like a good idea, keeping someone in the palm of your hand in more ways than they're actively aware of. So one day he tries it, gives it his best go despite the fact that they've never gotten along all that well. 

That he thinks Charlie is reckless and hardly worth the benefits he's afforded.

So with foreign teeth at his hips and hands on his thighs, he dwells,
and seethes,
and cuts too deep.

And it's an accident, he swears, bloody up to his wrist, sopping up more with spare bandages against the split curve of Charlie's left shoulder. But when Charlie wakes up the next day Frazer has to have a talk with him. Has to explain the stitches and the pain in his arm that he never went to bed with.

Wounds he can't remember winning that never stop turning up.
