You'd think that when Gene ends up in the same situation as LoM, he could hardly help mentioning Sam as another DI with weird ideas who turned up mysteriously... (I think it's Gene, he's magically sucking sidekicks from the 21st century)

I hope they don't say anything that spoils the this-is-DCI-Tyler-and-DI-Cartwright-Tyler-together-they-fight-crime...in Manchester scenario that should be happening off-screen.
