The third point of view
Eliot was still very angry with everything that happened at the party. He knew Elpis was behind this, there was no doubt. Alpha Silas suddenly changed his mind after everything, he knew something was up.
Eliot knew Elpis and Hemera were playing at something but he didn't know what it was. Ever since he met that girl he has been acting funny so Eliot tried to get her out of the way but it just didn't work; Elpis got to her before the guys could do anything. Eliot knew the consequences if he was caught so he got rid of all the men.
Eliot couldn't keep on lying to himself, he was scared. He was scared of Hemera. That was the main reason he wasn't to get rid of him. If she by chance finds out anything, he knows he would be done for any if there is anyone who could find it, it was Elpis.
