Poe straightened at that particular designation, and BB-8 chirped a query. Certainly there were other R2 units out there, not just the one that the General had more or less in storage, hoping that Commander Skywalker would come back and claim it someday.

He was sure that some of those other units were likewise referred to as 'R2' with that same sort of fondness, but something still pushed him to ask: "R2-D2? White and blue? Silver trim? Likes setting things on fire?" That one he didn't know from personal experience, only from stories, but it didn't surprise him any given as how astromechs only had limited defenses to work with, it was part of why BB-8 took an arc welder to anything it perceived as being a threat.
