Broke the host of moon cactus

[Alaska17]

Hello everyone,
I had a moon cactus in a pot on the window sill and today my roommate knocked it off by mistake so the host cactus snapped off a little. Can anyone please tell me if something will happen to the plant and what can I do? It snapped at the bottom so i couldn't get a good shot of it.

Re-settle it and maybe stake it upright. Cactus are really tough and the rootstock will develop more roots where it broke.
