The first cool thing he's ever done is kill you? Why is that hilarious?

[At this point, Will is still working on the assumption that "he" or "that son of a bitch" is not, in fact, someone inside Skyler, but an outside person that he left behind. His killer, probably.

Will is also aware of the slang for a sex act, but he's not making the connection here.]

At least you're not a child. That should make me feel less bad about giving you this, but I already didn't, because it's not illicit where I come from. Apparently that's not the case in most worlds.

[Your turn, Skyler. Puff pass dude.]
