she likely kept the fact that she overheard diluc leaving KoF a secret though?

"The Bridge only works now if people go on it in pairs and there are three possible scenarios that can happen:
1) The characters who entered the bridge will see each other as someone they lost."

this could be crepus & gramps

"2) The characters will see their worst enemy in each other."

"3) The characters will see themselves in each other, but either an idealistic version of themselves or something they would never want to see themselves become."

either of these prompts could be done too

"The barrier around the bridge will disappear once something truthful about the person they see in front of them has been said."

truth about her seeing him quit KoF goes here?

but yeah we don't have to, those were just my ideas when I read the prompt
