The first thing that really struck me was that that robot was incredibly similar to the opening scene robot, as mentioned. I think more important significance was what Ushio said, that it was the first thing Tomoya bought for her.

It seems as though we'll finally have a chance for Tomoya and his father to interact more. I wonder if he'll help his father get back on his feet before sending him home.

Will Ushio stay with Tomoya at his apartment or will he move back in with Sanae and Akki...err Akio?
