10 Things You Learn Re-Watching Brooklyn Nine-Nine

Captain Raymond Holt is an imposing and commanding figure, whose commitment to following the rules and his own moral code makes him an unlikely – and perfectly contrasting – mentor to our goofy protagonist, Jake Peralta.

From the very first episode, Holt is characterised as the "robot Captain". He rarely shows any emotion, something which becomes a running joke throughout the show, and it works.

The second time around, though, it becomes apparent that there is a much more subtle layer to Holt's personality that we only see in flashes: his love for his husband.

Holt and Kevin make a brilliant couple, that much is clear from the off. But what's easy to miss is just how sweet they truly are together, because it gets lost in the unorthodox dynamic they share.

Seeing them shake hands as a show of affection is a brilliant joke, as are their incredibly formal pet names for one another, but once you get a chance to see it all over again you notice not just that they are excellently suited to one another but that they make one of the sweetest couples on TV.
