"Rivals," or "Oscar is goddamn perfect"
We all know that Kieran is dense and beyond being reasoned with. So when sweet, quiet, unassuming Oscar wants to be helpful to the second-in-command of the Crimean Royal Knights, he throws all that “nice” guff out the window and just trolls the everliving shit out of him.
Kieran: We are equals. I need no favors from you! Run along, now.
Kieran: I don’t have the time to talk to you. I’m too busy training! Go on, leave!
Oscar: Ahem… It was meant as a symbol of friendship for my lifelong rival.
Oscar: But I guess if you won’t accept it, I’ll find someone else who will.
Kieran: Wait! I’ll take it.
Oscar: You’d swallow your own words?
Kieran: Ugh! Never! However… I note that your lifelong rival is me, and no one else! If your gift will mark me as your lifelong rival, I must have it!
Oh, Kieran, you fool. You don’t even realize you’ve lost this argument.
By the way, there is a degree of precedent with regard to Oscar being fresh when it suits him.
