Ambrose like immediately tortures Alaya to death, because she has bad ethics. This causes Tony to come down on her like a ton of bricks, because he’s her dad and thus has stronger ethics. Downstairs, Alaya’s twin sister is even more of a bitch than she is, and ties up the diplomacy party — Nasreen, Amy, the Doctor and Ambrose’s annoying husband — because she has bad ethics.
This causes the Silurian doctor — who last week dissected somebody while they were awake, for no reason — to wake up some sleeping dignitary, who comes down on Alaya’s twin sister like a ton of bricks, because he’s an old man and thus has stronger ethics. Meanwhile, the Doctor decides that he adores the Silurian doctor for not killing the freaky little boy, even though last week, as noted, the Silurian doctor dissected the kid’s dad while he was still awake, for no reason.
Lest you think the Doctor’s ethics have suffered, however, rest assured that he spends at least five separate scenes hammering it into Ambrose’s head what a disgusting, worthless, pointless, wretched, nasty embarrassment of a human being she is… And how amazing her son is going to be, thanks to her illustration of what not to do. (I guess we should just be glad that the Alaya sisters don’t also have some sons we could put our Jesus-y faith in.)
