Since the Awe activation was her Instant Action, another roll (Instant Action) can't be made. A roll with the Awe bonus can be made on the next Turn as her Instant Action (limited to 5-7 words to fit into a 3 second Turn).
Anyone with a Composure less than 5 is affected by Velma's Awe.
Xander , Leo is up // Leo needs to make a STA check // Please remember wound penalties on Actions!
