I was lately remarking to various people in comments that, by the end of Merlin, Arthur and Merlin "out-Frodo-and-Sam Frodo and Sam." But maybe it's a tie, to be fair. Now my mind won't rest until I've delineated all the items on the bromance checklist that both pairs seem to be using as their guidebook. Let's go!
Master and servant situation: check!
Save each other's lives a whole bunch of times (bonus points if you get soaked): check!
Also make verbal promises about continuing to save each other's lives: check!
Wear armor together even if that isn't usually your thing: check!
Play with ropes together: check!
Occasionally fall under evil magic influence and try to kill your bro: check!
Carry each other in case of unconsciousness: check!
Come around to seeing servant's mighty worth even if you took him for granted at first: check!
Hold your bro tenderly at the end and make us all cry: check!
Tearfully see him off on a boat headed for magical lands: check!
Yeah. I guess it's a tie.
I will go down with these ships. Bromances. Things.
