Hal Jordan / Green Lantern being your mentor would include:
> Being given a bunch of nicknames but his favourite is probably ‘Lil’ Light’
“You can do better than that Lil’ Light.”
“It’s (y/n). (Y/nnnn), say it with me.”
“How about Greenie?”
“Whatever old man.”
“Hey! Stick to Hal.”
> Forming a middle finger with the ring when Hal starts to bug you with his teaching methods.
> Hal thinking it’s quite smart the first time and why didn’t he think of that?
> The other lanterns looking out for you and helping you get out of training if Hal is going overboard.
“Kilowog, have you seen (y/n)?”
“Nope, try the Andromeda galaxy.”
“Cute, real cute.”
> After some tough training, Hal bringing some pizza or another food you like from Earth so you can relax a little.
> Meeting the Flash and other members of the Justice League, but since Hal and Barry are like best friends you see him more often.
> Hal being worried he’s not doing a good job.
“You’re doing great, (y/n) is really glad you’re their mentor and wouldn’t want anyone else.” Barry assuring him otherwise since you speak to him outside of hero personas.
“Seriously? (Y/n) said that?”
“Yeah, they may not act like it but (y/n) holds you in high regard Hal.”
> Doing Batman impressions after visits to the Justice League, Hal is surprisingly good at the voice.
> “The ‘will’ is strong with this one.”
“Kick your ass to the next galaxy, I will.”
“Got you to join in that time~”
> Going for flights at ridiculous times to learn new tricks that are occasionally irrelevant in a fight.
“I need a nap, 5 more minutes.”
“(Y/n), don’t make me come in there and drag you out.”
Flying out the window whilst Hal is still pacing outside your door thinking you’re not ready.
“Hah! You’d have to catch me first Jordan!”
> Hal being over protective after a while because he’s grown attached. He will deny that.
“You’re smooth right? Can you teach me a few tricks?” Having heard some of Hal’s remarks to female civilians.
“Yes, and no. You’re too young.”
“I’m basically an adult now!”
“Still too young to me.”
> Hal taking the wrap for you if you mess up, even against your protests.
> Getting nervous when going on solo missions because you feel more confident with Hal by your side.
“Can’t you come with me?”
“(Y/n), you’re amazing and your training is going so well that I have complete faith in you.”
“Hal I just don’t know.”
“In brightest day, in darkest night. No evil shall escape my sight…”
“Let those who worship evil’s might, beware my power - green lanterns light.” You finished the vow and took a deep breath.
Hal gives you a reassuring smile and nod before sending you off.
> Meeting Guy Gardener and John Stewart who think you’re a credit to the Corps. John talks to you about strategies and battle plans whereas you get tips on how to annoy Hal from Guy. But you don’t need any help with that.
> Being pretty good friends with Hal outside of the hero business.
> Your training may sometimes be just for fun but when it comes down to it, you’re the best team out of the Lantern Corps and you’ll protect each other at all costs.
