I'd leave it baggy in small/small, less likely to cause problems than accidentally going big/big when you're tired and exploding the mech.
It goes into it, the chain just rubs on the bit of the cage that's folded over.
I'll probably get a smaller cassette next time/if there's anything super cheap on crc!
