Narrator V2 AU loreee
{How am I still here? I managed to download a bit of myself to "MY" newer arm before that blue bastard arrived for our second duel. Sure, I was confident that I would win back then but juuuuust in case. Never hurts to have a backup y'know?}
So yeah. In this AU, just like what V2 said, after tasting defeat against V1, V2 makes a back up for majority of her data within the Whiplash arm, just in case V1 manages to kill her and take her new arm, which proved to be a good idea. As, that's exactly what happened. As soon as V1 attached the Whiplash to himself, V2 was able to enter V1's system. So, V2 can communicate with V1 (Only V1 can hear V2), and able to see through V1's eye. (V1 can only see the HUD, but cannot see the surroundings)
Anyways, since V2 is stuck in V1's body, V2 gets bored asf, and decides to narrate V1's journey and whatnot.
Later on, V2 does eventually gives V1 their vision back because the two got close and V2 felt really sorry about that.
YES, THIS AU IS V4V, NO I DON'T SEE THEM AS SIBLINGS. I SEE THEM AS RIVALS TURNED LOVER TYPE THING IDK.
