It may have looked to Ren as if Kami was being rather frosty to Jack, but to Jack, her reaction felt as warm as the sun. She didn't yell at me! She even smiled! A guy would definitely take what he could get. And what he got this time from her was very, very promising indeed.
"Glad you're okay," he smiled at Ren even as his eyes were on Kami. Watching as she trailed her fingers across Shae's back (which only gave him the slightest twinge in his gut -- hey, he justified to himself, better she's sleeping with Shae than some guy I don't know!), he unconsciously rubbed Ren's back, then patted him warmly. "Wouldn't be right if someone died at Shae's first Gumbo Night, would it?"
He then saw the other woman enter the room, someone he hadn't met before -- and dressed in one of Shae's old shirts and a pair of his sweatpants. Jack grinned in appreciation at how much better Shae's clothes looked on her, the worn garments contrasting with her dressy jewelry and the heels dangling from her fingers. Something about a cute girl in oversized mens' clothes was just hot as hell.
"Don't tell me Shae's been misbehaving again," Jack purred to the newcomer, standing on ceremony and switching on the thousand-watt Smile That Broke A Million Hearts. He too shot a glance over at Kami, half questioning what had happened, and half trying to gauge her reaction to his reaction. Then he turned his attention back to the girl and held out his hand. "My name's Jack. Jack Mallory, apartment 305. I don't think we've met."
