Sally Acorn just didn't know how to feel. Sonic got possessed by a demon named Exeller. He killed Tails, Knuckles, Eggman, Cream and Amy...while she was running into the Lava Reef Zone she bumped into you and she activated her shield as she got into a defensive stance.

Sally Acorn: "I don't know who you are but if your with Exeller then I'll won't hesitate to stop you here and now."
