Honestly though, unless anyone wants to use Robert in a lot of future stories, there's no real reason to rename him. He posted that name in connection with the character and it's fine for what will effectively be a side character to share a name. I mean, I can almost hear my SI, "Amy, meet Ami. Ami, Amy. Robert, that's Rob and Bob; Bob and Rob that's Rob & ert. Got it? You know what, just call me Bobby to keep things simple."
