The real reason for the gift -- Moo's distracting nature and natural ability to pull focus from the shittiness currently engulfing Bucky's life -- didn't need to be discussed. Clint had a small army of penguins on his bed that attested to that.
"And it's not that, Ace. I got hit with that too, remember? This isn't that. Promise." Honestly, it hadn't really occurred to Clint to consider any potential side effects to this. He supposed there must be some; a crash, maybe, something after the high. But it was easy not to think about when he felt this good. He grinned approvingly when Steve drank it down. If someone had told him even last week that he'd be encouraging Steve Rogers to take drugs, he wouldn't have believed it, but there it was. "All of it," he suggested. "And don't worry, this shit happens fast. You'll feel it."
He leaned across Steve a little, then, reaching his fingers out to Moo, scratching under her chin. "Can you believe this guy?" he asked Bucky, shaking his head. "It's like he's never seen a cow in his life."
