Castiel cleared his throat, looking back up at Dean. His cheeks might feel suspiciously warm and he might be more embarrassed than he'd been since that one memorable day in high school, but he was going to play this off, damn it. "Whatever's on tap is fine, thanks."
He couldn't be entirely sure, but he thought he saw the green eyes in front of him widen a small bit.
"Awww, come on Cassie!", Gabriel's smile looked suspiciously shark-like when Castiel turned his head. "We're here to forget our woes! You need something stronger than that!" He leaned towards Dean, adopting a stage-whisper. "Cassie here has the tolerance of a Russian lumberjack, so you might want to hit him with the really strong stuff."
Dean chuckled, eyes glancing over to Cas before replying to Gabriel. "You promise me you're not going to give him alcohol poisoning?"
Gabe gasped dramatically, throwing his hand up to cover his heart. "Why, Dean Winchester! You think I'd hurt my little bro like that?"
Cas rolled his eyes. "Yes. You've done it before." He narrowed his eyes at his brother. "You've done worse before. I still haven't forgiven you for the bleach incident."
Gabe cackled, "But you looked great as a blonde, Cassie!" He turned back to Dean, "Anyway, Dean-o, give him a whiskey, neat. We'll go on a refill basis, so you can cut us off if you think we're getting too far gone," he winked.
Dean shook his head, still faintly smiling at the brothers. "Fine, Gabe, let's go with that." He started pulling out syrup bottles and alcohols, no doubt all for Gabe's frou-frou creation. "So, Cassie, huh?
Castiel groaned and thunked down on the bar and Gabriel cracked up again. "No," he said to the floor, slightly louder so Dean could hear it over the music. "That's just what Gabriel calls me." He lifted his head and started to reach across the bar for a handshake before he realized Dean's hands were full of bottles. Hand already up, he hastily changed it to an awkward wave. "My name is Castiel."
"Castiel." Dean said thoughtfully, trying it out. Castiel was rewarded with a crooked grin, "Awesome. It's angelic, right?"
Cas was a little dazed by the smile, but managed to breathe out a, "Yeah."
Dean set Gabriel's drink down on the bar, pulling out a small glass and a bottle of whiskey. "Well, I'm probably gonna call you Cas, okay?" He smiled as he poured the drink. "Harder to mess up that way." He winked before moving down to the other end of the bar to serve a couple new arrivals.
"Soooo…", Gabe drawled, turning sideways in his seat. "Dean, huh?" His grin looked like he was having the time of his life.
Cas' head was suddenly back on the bar. "No."
"Come on, bro, you think I didn't see that?" Cas couldn't quite see, but he was pretty sure Gabe waved his straw around, from the drop or two he felt on his arm. "The whole bar could see that! Your eyes were sappier than a maple tree."
Castiel groaned. After a minute, he sighed and lifted his head. "Please don't try to play matchmaker. For all we know Dean is in a lovely, committed relationship with a nice woman. And," he glared at Gabriel, who had opened his mouth to interrupt, "even if he isn't, I doubt I'm his type. He works as a bartender, he's personable, he's," Castiel blew out a breath and glared at his drink. "He's beautiful." He grabbed the glass and downed it in one go, wincing at the burn. "And I'm… me."
Gabriel rolled his eyes. "Yo, Dean!" He yelled down the bar.
Dean glanced up at him, not pausing in mixing the cocktail the giggly girl in front of him had ordered. "What, Gabe?"
"Do you like dick?"
Dean laughed, handing the girl her drink. "You're lucky this is a tolerant bar, man!" He walked back over to them, wiping his hands on a hand towel as he went. "But, yeah," he said, still chuckling but at a normal volume. "I'm bi as hell. Why?"
Gabe just shrugged as Castiel's face burned. "Just wondering."
Dean gestured at Cas' glass, "Refill?"
"Yeah," he said, running a hand over his face. "Keep 'em coming. I think I'll need it." He glared at Gabriel, who gave him a cheeky wink before sipping his cocktail.
