Of course BB-8 did that. Of course. Poe is struck by the sudden and impossible urge to strangle something that doesn't actually have a neck. He knows it's a temporary surge of irritation, but this is all too much. He's generally not a guy embarrassed by his sexuality or expression thereof, but it's still one hell of a line getting crossed when it ends up with someone rooting through his sex toys at the behest of his droid. That it's someone he has a crush on and doesn't know how to approach is just the cherry on a crap sundae.

There's a long stare at Finn and BB-8. Then Poe says, "You guys feel free to argue about whose fault anything is. I'm going to go check our course."

Yes, this is him running away. Strategic retreat. Same thing.
