Ernie and Hannah
Ernie looked around for a moment before catching someone waving at him and realizing that it was Hannah who had been waiting for him. He had a bit of a double take when he was scanning the steadily growing crowd for Hannah. He saw Cho as he entered, and waved before continuing his search.
Upon noticing Hannah, Ernie gave a relieved smile that his delay didn't appear to put a damper on her mood. "You look beautiful," he said, as he approached her, slowing down to take in the sight, before giving her a peck on the lips in greeting. "I hope you weren't waiting for too long. It has been a rather busy day, what with ensuring that old witches and wizards aren't hexing muggle children and with this. How's been Lavender doing lately?"
