Sylvia was stunned and pretty ecstatic when she found that she can now straight up use magic, even if it's only just radiant energy bolts, and she can catch missiles now. She was somewhat surprised to hear that a memory came back to Buddy, a memory of being trained by monsters and various beasts. Her surprise was strongest at the mention that he wanted her to try and possess him. 

The thought of being possessed scared Sylvia back home, but her possessing Buddy? She wasn't sure what to think of it. Since he was willing, there wasn't really an issue. Plus, her morbid curiosity was now kicking in. What [i]was[/i] it like to possess someone? His theory about the memories wasn't too far off, if the memories she saw were anything to go by.

She approached Buddy and she answered, "I hope this works! Now, I just figure out how this possession thing works..." She tries touching Buddy on the chest to see if there would be any reaction, or see if she could possess him by walking through him.
