it's winter, making it so insectoids are stuck inside their homes, with Fritz and Sean bunkered in, and Sean, a human Fritz and other insectoids are obsessed and possessive over (due to most humans being seen as extremely dangerous, and are killed or captured on Sight, but Sean was seen differently due to how friendly and innocent he is, so they currently want to keep him from human civilization) tries to go outside, and squeaks as Fritz drags him away from the door, clinging to his warmth instinctively since Fritz is cold-blooded, and Sean is warm-blooded, so Fritz is of course clingy towards anything warm.
