I like that they covered the whole Kelvin fight this episode (they even skipped the opening to get more time) instead of having us wait for the result.
So Kelvin had been holding back (way back, as we'd find out later in the episode) in his fights to entertain the viewers, a fact he admitted to Rick whom I guess he felt is worthy enough.
But he finally met Broughston who was stronger, and he gave up his hesitation and went all-out after some encouragement from the gym owner. Turned out he was strong in magic also, which took a lot of hard training. He used level-eight magic which impressed the S-rank party members and a big reaction from Angelica. Broughston for his part showed his respect by giving the champion the orc quarter thumbs-up and then beat him utterly.
It went into the ending song right after the fight, so we don't know how Rick's reacted to having to fight Broughston next, I doubt he'll be let off easily just because they have secured the belt :-)
