LOLOL, Eliot's got a fairly high alcohol tolerance even if he's curbed his drinking some since his last party (turns out it isn't fun having to panic about a teenager when plastered). Eliot definitely welcome Anakin and definitely noticed the tie. It made him super happy, tbh. He'll also thank Anakin for the droid!
Hah! Well, Eliot actually is fairly okay with his other self. He'd definitely be willing to introduce the other Eliot to Anakin. There might be a slight hesitation while Eliot tries to figure out what to call Anakin, because they've not told everyone about his engagement, but it's only a skip of a second that Eliot 2 might notice? But if Becky is cool with it, Eliot 1 will somehow introduce Eliot 2 to Anakin. "This is Anakin Skywalker, Kylo's Grandfather" more or less. The introduction Eliot is far more excited about and would likely insist Anakin follow him for would be Fen. He'd be talking to Anakin as they approached, apologizing that Fray isn't here and explaining how she's gone on the survival class trip this weekend, before being like "Fen!" Anakin gets to meet Fen at a time where Eliot's demeanor toward her feels less arranged and more affectionate.
He'll be paying attention to Anakin and Kylo throughout the night and hoping all is good on that front.
