Neville had just walked into the kitchen, having been in the greenhouses when he heard first, rather than saw, Fred and Katie. It's quite a good thing that he had been working with roses and thorny items that morning because his lip was still healing from when Ginny nearly bit it clean off. Though he was sure he'd be teased in any case.
"Fred! Katie! You're back... Congratulations you two. I'm guessing you had a good time in Switzerland since we haven't seen you in a month!" Neville beamed and walked over to greet them, having cast a 'scourgify' on himself before exiting the greenhouses.
He gave Katie a warm hug and a kiss on the cheek, and Fred a hearty handshake and a healthy pat on the back. "Is there tea on? And would anyone like another cup?"
