it's winter, making it so insectoids are stuck inside their homes, with Vi and Sean bunkered in, and Sean, a human Vi 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 Vi drags him away from the door, clinging to his warmth instinctively since Vi is cold-blooded, and Sean is warm-blooded, so Vi is of course clingy towards anything warm.
