Establishing shots are hard.
While I doubt most readers would notice or care, I do my best to maintain continuity on where characters are standing relative to one another at all times. This hasn't been such an issue in the prior two chapters, where most scenes were just between Leon and Trinity/Luca, /maybe/ one other NPC... but now (and likely, for the rest of the story), we have a lot of shots involving at least four characters.
Hence the need to remind myself on occasion where everyone is and will be going relative to one another.
