It's not properly Milliways before something totally cracky befell the character, some ridiculous thing that is totally beyond their reach and fundamentally fails to take them seriously. Lecter should be paired either with somebody intentionally cracky and annoying he then can't go ahead, butcher, and eat (dare I think along the lines of Vyvyan here?) even though he might try to and then see he just can't (I can just imagine the fallout: afterwards, Vyvyan to Teja: "Oy, that tosser tried to kill me!"; Teja to Vyvyan: "Any sane man would have, merely for a moment's peace: - even if you spoke the truth, which I doubt, I could not fault him!"), or with somebody fluffy and annoyingly harmless whose constant presence would force him to be 'good'; here, I might be thinking along the lines of pony or sweet little non-Karkat troll...

But while they're handcuffed together (any charries, really), how the hell do they a) go to the loo and b)change their shirt?
