I always get all these thoughts in my head and 'm not great at articulating them, sometimes. Buck's the outgoing one, always draggin' me along so I don't stay cooped up in my apartment, shuttin' everyone out. Not that I do it on purpose," mostly, he silently added, "I just get lost in my own head a lot.

"Anyway," he shrugged. "We're kinda a package deal. Even if we weren't soulmates, he's been there basically my whole life, so he's... like my brother. My obnoxious, really annoying brother sometimes," he joked, casting a grin at Marie. "But he's a constant. So, I figure... an' I mean, he'll definitely want to meet you too. He actually wanted me to go out tonight with him. 'You never have enough fun, Stevie,'" he paraphrased, in a rather close proximity to Bucky's usual cajoling drawl. "Boy, is he gonna be surprised."

'Surprised' probably severely underrated how shocked - and delighted - Bucky would end up being when he met Marie.
