Or maybe they could plan to meet up that evening and Ellanor brings Jude, who sees what's going on, doesn't like it, tips of the "real" boyfriend, etc.? I'm thinking he's already met Chris, and either doesn't tell Ellanor, so she introduces Ari as her man, or Ellanor knows, and so introduces Ari as a friend, but Jude isn't stupid.
Either way I could just skip up to that evening in my post. What d'ya think? :3
