She starts crying.....
Alice : Kate....
Cardinal goes to her....
Cardinal : you have..to keep going, life isn't easy, but we have to NOT stop, Okay?
Alice wipes out her tears....
Alice : okay....
As they're walking back....someone appears behind a big rock...
*Footsteps*
Cardinal : ....!!
??? : this is the endgame.
Time stops....
??? : i've tried so many times to win, but in the end...i always lose.
The person takes off their jacket...
??? : this time...i'll win.
Time resumes and now they're wearing knight armor.....
??? : wouldn't you agree....cardinal?
Cardinal : you are....!
Cardinal : SKYLA!

Cardinal : (Skyla...when did you come here?! I'm sure nobody was there..! What the hell is happening?)
Alice doesn't know who's skyla, and she is surprised....
Cardinal : ( but i am sure....she is from that time....30 years ago!)
Flashback...
Kate's theme : Fear..(Skyla's version)

Skyla : (30 years ago...i joined the integrity knights, they were nice days, until i found out who killed my family, it was the administrator..., she erased my memories from this world i couldn't remember anything, so i took my sword, it's called "The Ruler", it is invincible, no one can defeat me, not even beroucli himself, but...)
Cardinal : ( the administrator was full of rage, she wanted to KILL Skyla for her betrayl, Skyla ran away after killing 4 integrity knights, and hid in the wild as a traitor...)
Cardinal : ( i made two mistakes, the first one...was to follow her, thinking she was a good person, and the second.....)
A fight scene showing Skyla stabbing cardinal...
Cardinal : t-time...?
Skyla : i stopped it.
but cardinal managed to run away.....
Cardinal : ( was to underestimate the power of her sword....)
Flashback ended....
Cardinal : Don't get close to me! I am up here! And you're down there!
Skyla jumps to Cardinal...
Skyla grabs her gray sword, the "Ruler" a sword that has a wheel in the middle of it, when the wheel stops, time will stop....
Skyla : you're the one who's down! As long as you belong in hell...it won't matter even if i kill you!
Cardinal : water element....
