[Jack is a light sleeper--surely Angela knows that, or perhaps she just hoped that he was finally getting some real rest. He hasn't heard the entirety of the conversation, but for someone like him, it was only a matter of time before he was roused. The real skill is continuing to appear asleep while listening to the conversation, which he does, of course. It's nice to hear Angela uncensored, not tiptoeing around his feelings, although she does refrain from actual anger. He still finds himself wishing she'd just let herself be openly hurt.

He isn't angry that Angela is telling Snake. Even asking her to keep his secret is unfair and impossible, so he doesn't blame her for needing a presumably unbiased third party. Knowing they're at least a little bit close is more a surprise than hearing her explain the situation. It's that curiosity that causes him to keep pretending for a little longer than he probably should.

Eventually, however, he knows he needs to give up the ghost. Joining the conversation is not polite, but it's worse to eavesdrop, he thinks. That's what has him getting off the couch (slowly, so as not to aggravate his injury) and making his way into the kitchen.

He's a far cry from the vigilante that Snake is perhaps used to, wearing loose-fitting clothes more suited for lounging around a house (which he seems to have been doing), the mask and tactical gear and giant rifle nowhere to be seen. Still, his presence is not insubstantial and he still fills most of the doorway. He speaks up to announce his presence.]

You don't have to cut me any slack.

[Sort of. Jack still has a great deal of reasons for why he did what he did, but he knows none of that will fully legitimize what he did. Still, hearing an unbiased third party confirm that Angela has every right to be angry sort of helps him put things into more coherent words.

He sounds tired.]

But they would've brought you all down with me. You've got plausible deniability if I'm dead.
