"Lemme see," he says, and grabs Peter's hand, because he wants to, and that's something he can do now. Peter lets him.

At first it feels like any other wrist, but once he finds the pinprick hole at the base of Peter's hand, Frank can't unsee it. He rubs his thumb down from the opening, and the spinneret feels like a particularly big vein. Tender, pressing bluish against Peter's pale skin, and warm from the coffee mug. His hand fists against Frank's sleeve, then relaxes.

Frank glances up from where he's leaning over the table like this is something that needs his undivided attention. "Hurt?"

"No," Peter says, from somewhere deep in his throat. He's staring again, at his strong, flexible wrist in Frank's fucked up hands, big and square and scarred. "Just doesn't feel like that when I touch it."
