Ben and Ronan had arrived at the party and after saying hello to everyone he knew--which was an awful lot of people actually--and getting a drink--water for Ronan and champagne for Ben--they'd spent the early part of the evening dancing (and snogging) and generally being amused at the decadence on display. It suited Eros, Ben thought, pressing closer to Ronan as they made their way through the crowd. And it looked from the surprise on Patrick's face that it suited him too.
He was planning on making his way over to Patrick, wish him a happy birthday and give him the small gift he'd brought, but he noticed someone else before they made it. Grinning happily, he leaned up to kiss Ronan before whispering, "Come on, there's someone I want you to meet!"
He tugged Ronan with him, not that it required much effort--Ben was thrilled with the way Ronan had stayed close, showing off that they were together. It was helped along by the dark mark completely visible on his neck, and a matching one visible on his hip every time he raised his arms so his shirt rode up.
"Chris!" he called out, bubbly and joyous with more than just the champagne. "This is my...Ronan. Ronan, this is Chris Creevey, my honorary little brother."
