I've seen theories that olruggio's alcoholism is because of unrequited love or the memory thing but like. I saw him as a child—gay AND traumatized AND unmedicated adhd AND gifted kid syndrome AND a saviour complex AND from a frozen, mountainous hellscape?? That alcoholism was calling to him like the green goblin mask; he's actually doing a great job keeping it under wraps. Only like one bender a month? He's fine

Olly literally said: I'll be your hearth, I'll be your safety, I'll be the place you don't have to lie. I'll light your path, I'll be the eye you lost, I'll watch over you. I'll be anything and everything you need if you'll only let me. And still then, even when you won't. Even if you beg me not to. I'll be your greatest comfort and greatest sorrow. I'll be the reason you're still alive.

Qifrey is afraid of water/hates getting wet. Olruggio has thumb rings with a spell to instantly dry things. Which could mean nothing.
