"Hey! Language," Rocket chided, a knee-jerk reaction to Groot's inappropriateness in front of the waiter. He was grateful for it, though, because it allowed him to fall back into his gruff, cranky persona, even if it was a mask right now. A mask for his pain. It was all he could do not to demand Groot let him move into his bedroom just so he could watch him at all times and feel sure he was still there.
Seeing Groot drink his cocoa like a little boy made his heart swell, though, and a happy grin stretched his features even as the image before him dispelled the dark clouds in their mood. He did lean far forward in his seat, seeing as he was quite short for an adult human, to ruffle Groot's hair affectionately. "Is it? Looks like it."
His own cups of cocoa arrived and he took a near scalding swig of the sweet concoction. Whoa! Things tasted... different on his human tongue. He couldn't quite decipher it. It was sweet and thick, almost too sweet. But he didn't care, because even though it burned his tongue a little, the hot chocolate warmed him up from the inside out. He heaved a great satisfied sigh and sagged in his chair, his eyes hooded to half mast. "Oh, yeah. That's good!"
