Start of fight
Past You whispers: Whoa! You're me, but from the future! Hey, my equipment got an upgrade! Cool!
Past You whispers: Here come the Infinites! I've got to keep the hourglass safe. Can you help?
During the fight some combination of the below
Past You whispers: This equipment looks cool and all, but couldn't we have done a little better? Are you even raiding?
Past You whispers: Chromie said that if I don't do this just right, I might wink out of existence. If I go, then you go!
Past You whispers: I just want you to know that if we get through this alive, I'm making sure that we turn out better than you. No offense.
Past You whispers: Looks like I'm an underachiever.
Past You whispers: Wait a minute! If you're here, then that means that in the not-so-distant future I'm going to be you helping me? Are we stuck in a time loop?!
Past You whispers: I think I'm going to turn to drinking after this.
After the fight
Past You whispers: What the heck? Nozdormu is up there!
Past You whispers: I feel like I'm being pulled away through time. Thanks for the help....
