Steve wasn't awkward at all when Yelena didn't shake his hand. He was no stranger to being snubbed, even when he was in uniform in his own universe. Waking up in this world in street clothes had honestly been a blessing. He sat back after releasing a quiet breath and grabbed one of the bottles in front of Buck, regardless of the fact that a) it was half-drunk and b) it did nothing for him.

"I'm sorry, I didn't mean to interrupt your conversation. That was pretty inconsiderate of me. May I buy you another drink to make up for really putting my foot in it?"
