Its almost surreal that the LL comic is done! You left me happily shocked with the end. I'm interested in writing about it, in fact, and I wanna be true to the lore, so I'm asking the burning question—what would have happened had Grey's code gotten too corrupted? If Glitchy Red had found him too late?
AAAA tbh I'm still taking in the fact that I finished that comic myself haha. It's not like I'm done working on LL stuff, far from it in fact, but having been able to stick to a comic for that long and actually bring it to a close despite all the clean up is a huge milestone for me.
Uuuuuh anyways, your question. First of all, I'm scared for what you're intending in cooking up ksdfgjns (joking of course, go ham my dude). Second of all, oh man...
I would say that his body would almost get disintegrated by how much the corruption would have disrupted his body.
The remains of his body would be barely kept together by his soul. He would lose his voice. He wouldn't be able to hear anything if only muffled noises. He could barely see anything. He would barely feel anything.
In that state, he would probably still be salvaged and mostly restored if returned to his game, but it would take a very long time to even bring him back to the "living", if that makes sense.
And if he loses his body completely while being in GR's game... well... his soul is not compatible with that game's code, so it wouldn't be able to persist for long...
I do have to say that this may change in the future, I didn't really thought much at what would happen in detail back when I worked through the comic, so some elements could change as I refine the idea. But yeah for now it's this.
