Now Iook like an idiot, because I haven't mentioned Mai Mai, Mai's younger sister who has been a comic relief nuisance underfoot this whole episode.
And the post credits scene reveals that it was all a mistake. Shirley had been sent to bring Mai Mai home, not Mai.
Lol?
There's a preview for a third episode, but given that it features a mecha-reindeer, I'm assuming it's a joke that was never intended to be real.
