The point is, if anyone visits the Bakery, they'll find it... surprisingly unprepared for such an important day. Like, there's only a small handful of chocolate cakes ready; some where the cake layers seem to have been baked; a couple of bowls with frosting sitting abandoned on the counter.
And then there's Sebastian, engaged in the very non-Sebastian-esque behaviour of Not Working: instead, he's sitting (!!) on the hitherto never-used chair by the counter, petting a cat in a surprisingly lackluster way. He's not even wearing an apron.
