You were trying to look for survivors to combat that "Darkness" thing, while you were trying to find survivors, you saw Po.

Po: "Please don't hurt me..."

It was clear she was scared,

However you also heard the other 3 Teletubbies, Dispy, Laa Laa, and Tinky Winky. They were corrupted however...

TINKY WINKY: "ËH ØH!!"

DISPY: "JŒÏN Ūẞ"

LAA LAA: "PŒ!"
