"So, is he always like that?" Blaine asks.
Sebastian has gone, and Blaine and Kurt are busying themselves tidying up in the kitchen.
"Like what?" Kurt asks, not looking over as he scrubs at a pan in the sink.
"Just, so… forward. He was kind of flirty with you is all." He tries to make it sound casual, like he doesn't care, like it hasn't been eating at him the whole evening.
"He wasn't flirting with me," Kurt says, continuing to scrub intently.
Blaine bites his lip, pauses a moment before he speaks again. "Some people are just like that with everyone," he says. "It's fine if he's just like that. You know I'm not – mad, or anything."
Kurt sighs lightly. "I guess he's… a bit. But it's nothing, really."
"I know," Blaine says. "I know. I was just curious."
They clean in silence a while longer before Blaine speaks again. "He seems nice."
"Yeah. He is."
"And I guess I can't really blame him," Blaine adds, crossing the room to approach Kurt, wrapping his arms around his husband's waist and pressing his chest to his back. "I'd be flirting with you too."
Kurt turns to catch Blaine's eye, and Blaine plants a soft kiss to his cheek.
This is fine. He has nothing to worry about. Kurt is here and in his arms. Kurt is his. And Kurt is allowed to have friends.
Even if those friends flirt with him.
Even if Kurt might like the attention.
At the end of the day, Kurt is still his, and his husband is the happiest he's been in a long time, so Blaine will just need to learn to get over his insecurities. He trusts Kurt. They've been through hell together, and they've stuck it out this long.
If he can't trust his husband, then what does he have left?
