Maizie
Maizie is totally there, rocking some kind of Holiday sweater and saying hello to all her friends in attendance! And also probably playing with the babies and Mia because that's her jam. Her white elephant gift is a 3D Minion puzzle.
Open to handwaved interactions, so let me know if you character spoke with her or saw her playing Go Fish with Mia -- or if they joined in! Definitely here for saying that hanging out happened.
