"Hey!" Remus perked up even more as soon as the door opened. "They're, uh, busy right now." He plastered a smile on his face and moved inside without being invited, doing a spin around the foyer or whatever his house opened up into. "Listen, Pete, I've only got a few minutes but I need to talk to you."
There was no reason to expect something bad from this. Remus was clearly happy and excited and he even thought about toning it down, but that wasn't happening simply because he couldn't. Instead, he slung an arm around Peter's shoulders and leaned in.
"Look, so, Sirius and I are uh, kind of, er, together. Dating. Sort of." Honestly, he had no idea how to put this or how to make it 'gentle'. He definitely wasn't going to use the word snogging. "We just thought you should hear about it in person from one of us!" That was good, wasn't it?
