First off, every time the possibility of Eljay and Alena being in a relationship has been brought up, Eljay has vehemently stated time and time again that he is not Alena’s boyfriend (not matter how much Alena states the contrary). So that’s a proverbial red flag.
Secondly, Eljay said “girlfriends” plural, and then mentioned only one name, specifically “Alena”.
