There's a moment of confusion, clear on his face, but then the cloud lifts. "You're right. You're probably right."

Caroline is not the only terrible liar in this scenario. It's all Poe can do not to look at the cameras as he leads the way into the house. BB-8 rolls out from the kitchen, starting to ask Poe what the noise outside was-- and then chirps a greeting to Caroline instead of finishing the question. Poe reaches down to pat the little droid on the way to the bedroom.

He sits down on the bed, then lays down on it, barefoot as he already was. Easier to climb that way. "Why don't you come lay with me?"

This is the least awkward setup for a thing ever.
