Also friends with Strega Holowitz, Angela Mindock and Remi Gilmore. Elijah throws big parties and has blood transfusions at the hospital. He is a vampire. Or is he? He is. But is he? Yes

History
In episode 16 Elijah threw a party at his house, which The Interns and most other teens from in and near Thistlewood attended. At the party, his grandmother Valencia escorted most of the teens down into the family dungeons for a traditional coming-of-age ritual for Elijah called The Great Rest. The Interns immediately concluded that this is something vampiric and dangerous, their assumptions seemingly confirmed by Valencia refusing to let them back out and flashing fangs at them. They fought with Valencia near a demonic shrine while elsewhere in the mansion Fliss disrupted a number of DiSavonas doing very vampiric things and fought with them in a church. This fight was interrupted by Elijah who was horrified and embarrassed by the entire event. It turns out the ritual was mostly just hanging out in a sweat lodge. He thought that he just had a weird blood disease and wasn't a vampire, but the rest of the DiSavona clan rather awkwardly confirm that he is one, just none of them are especially murderous.
