Eugene was assumed to be Belial's contractor before Mars (Leviathan) killed him for "killing" Catherine (was not Lillith yet). He slit her throat and she was out for an entire day. When she returned and released her pent up anger for the way Mars was treating her, he finally recognized that she indeed was his contractor from the future. Eugene was captured by Mars, and Mars warned Catherine not to go in multiple times, but we all know she does what she wants lol Part of the reason he loves her <3
He's Eugene! Yay! We get to see him again! Also, fuck Behemoth for cutting in line!
