That is clearly an alien over there just casually dumping out food, not that Rick particularly cares. About the alien thing or the food, if we're keeping track. He's never been bothered by aliens unless they're trying to kill him, and he has his suspicions about all the food anyway.

Incidentally, the same suspicions do not apply to the alcohol laid out on the table, which he is consuming with abandon. Though he's also, like, scooping liquor bottles onto the floor at the same time? For some reason?

"Hey," he calls out to her, waiting until he has her attention before tipping a bottle onto the floor. It cracks from the impact, though it doesn't shatter into a zillion pieces or anything. Shards of glass are things he'd like to avoid, frankly. "Here's some more for you to clean up."
