>>104357810You're leaving very key facts in there, friend-o.
First, Hal threw a huge fit after learning that he wasn't Abin Sur's ring's optimal choice for a replacement, Guy Gardner was, he was just the closest person at the moment and since Abin was dying and needed to pass some important messages to his replacement before dying the ring prioritized him over Guy.
Then Hal started to stalk Guy before finally trying to strike a friendship with him, with this leading him to disclose about his life as a Green Lantern and Guy becoming his side-kick of sorts, since back then Guy was a upstanding and wholesome gym teacher.
Because Hal is a general fuck-up he ended up endangering Guy's life many times, with Hal's reckless behavior leading to Guy getting knocked into a coma after having a Power Battery blowing up in his face.
Like you said Guy wasn't merely in a normal coma, but had his conscious stranded in the fucking Phantom Zone, where he ended up being tortured daily by general Zod and his crew.
Hal, being the good guy that he is, started to fuck Guy's fiancee, Kari Limbo, who was a psychic gypsy like you mentioned.
Hal, of course, didn't wanted to marry her, but she ended up falling hard for him and started to drag Hal into that whole wedding business. Hal feeling guilty over the whole thing ended up biting the bullet.
Meanwhile back in the Phantom Zone general Zod was constantly torturing Guy over the fact that his friend was fucking his woman and cumming inside her every day, all day, because general Zod is a huge fucking dick.
Kari Limbo, being a psychic gypsy and all, managed to sense Guy's distress and pulled everything off, disappearing in her overwhelming guilt.
Hal, though, gave no fucks and kept on trucking.
