Because he's a nice guy, the Yeti puts the daughter down, so she runs to a phone booth to tell the eccentric rich guy that the Yeti is nice and is following her around. The police surround the Yeti but decide not to attack it, I assume this is because this is canada and not the USA.
We learn the Yeti has decided to pass out in a warehouse; we think he's sick or something. The Fourth Doctor and Yellow Jacket guy come to investigate, bringing an odd oxygen machine to revive him.
