its tighnover

not only because I think he definitely wears the pants in the relationship but I also think that, even if he won't admit it, it warms the cockles of flins' heart.

he's always leading expeditions into the abyss and he keeps everyone sane while they sleep! he gives them good dreams to protect them from the abyss

flins is so busy trying to hide that he isn't human that he doesn't even consider that ILLUGA might not be human

we know that flins hibernated for like 300+ years, so he's used to being asleep

illuga probably uses this to his advantage. when flins forgets to do his reports, illuga gives him extremely detailed dreams about what will happen if he doesn't file the paperwork. miraculously, flins always seems to turn them in the next day! what a coincidence

before the final battle, illuga sends dreams of winning to everyone in nod-krai for good luck

flins tries to hide his fae identity. he's so careful about it. meanwhile illuga is out here being like "oh yeah what do you wanna dream about tonight." he's out here using it as a weapon in combat. he's out here naming his squad the NIGHTMARE ORIOLES

somehow flins still doesn't figure it out

"young master for some reason i always dream about you right before you come to visit me." "hmm i wonder why!!"

I can imagine Flins and Illuga going out on patrol together and something like this happens:

Flins: The darkness is quite consuming tonight. It's difficult to see.

Illuga: Here, hold my hand so we don't lose each other

Flins: Ever reliable as always, Master Illuga 😊

Or something like this:

Flins: I admit I am feeling quite unwell. But it's alright Master Illuga, at least let me escort you.

Illuga: You're unwell?! absolutely not, Sir Flins. You must rest. Here, i'll make the bed and bring you some tea.

Flins: It's quite alright, don't worry about me. [stumbles]
