Harry/Peter
Harry was busy dueling back a witch who looked particularly wide-eyed before beating her back through a window of the pub. Then he saw her- a woman. A shadow coming at Peter and Harry knew that look. He recognized that pause- but luckily, someone else got her first- a spell hitting the shadow, sending her into a wisp of noting.
And he breathed again.
"I'm sorry," he whispered back and met Harry's eye. "I don't know what they are- I haven't seen magic like this before, but we'll find out."
Around them, the attackers were scattering. The shadows were disappearing. Things were calming once again, but there was still that feeling in his gut this was very, very bad. His hair stood on end and his eyes scanned the room.
