It was quite possibly the misleading setup to Sirius explanation to blame, but Remus could not have guessed the end of that sentence. How casually Sirius noted that he had an engineering doctorate made it sound like a punchline to a joke Remus hadn't been expecting. It left his lips parted for a moment before a smile eventually replaced his expression of utter surprise.<br/>"Do you really?" Remus pressed, floored, before he even got a chance to consider whether or not the phrasing of his question might be off-putting.<br/>Thoughtlessly, Remus leaned forward in his seat, nothing to gain from it but a better understanding of his childhood friend. Remus had always been impressed with people capable of finishing a degree, and the fact that Sirius had finished at least three had him completely smitten, the smile remaining at the corner of his lip.<br/>"Doctor," he mused, grinning as if explaining the joke to himself. "That's brilliant, Pads, well done."
