Suzanne Please explain, what the hell is going on here?

Marty Well clearly this is me throwing a fire ball!

Dad Feet are obviously still giving pain judging by the facial expression.

Trish You're fireball hasn't had much effect on Christine! In fact I would go as far to say she is laughing at you!

Marty Clearly this is just the moment before the fireball has been released, shortly after, she was floored!
