Characters seem to have revenge voice lines

Though I have no idea how to replicate them. I tried to let a bot kill me 5 times so it can be my nemesis, but it didn’t work. What triggers it?

JD: Oh! Payback’s a b*tch!
Now we’re even!

Lizzie: Revenge is a dish served however I feel like it!


I don’t think I ever heard the lines, were they usually in Horde?

Versus. I was killed by JD and he said “Now we’re even!”

Forgot to record it, but I can’t make that Lizzie one up, lol.
