Rosencrantz and Guildenstern are around now, as are the players. Ophelia is very focused on Hamlet and his internal struggle, to the exclusion of pretty much everything else in her life. Since this is from her point of view, it’s hard to tell what else might be happening with Hamlet. Are the adults remotely aware of what’s going on? How could they not be? Yet from what Ophelia is telling us it seems like they’re all missing it entirely, which is odd.
