Lance and been dodging multiple attacks from Peril's Evil Eye Curses, which are able to fire highly concentrated beams of energy from their pupils. The evolved hands of death were also attacking, and Lance was struggling, barely being able to avoid both things at once.
Rot: I never asked for or needed your help. (Rot said calmly, but his words were one of anger)
Peril: Dawnbreaker sent me packing, so I thought I'd help you out... You don't mind, do you Rot? (Peril asks in a sinister manner)
Rot: Not at all. (Rot said in a calmer manner, before he watches Lance fly around desperately to avoid their attacks)... (Depressed Sigh) I really wanted to face you alone, but it appears that luck just wasn't on your side. As with all the unfortunate humans, you will die a sad death... But afterwards, you shall know peace. (Rot thought as he watched Lance struggle)
