all three of them were at a club Alastor was the only one that had to be forced there by Angel Dust as the replacement for him

Only reason you are there with them is because you're friends with two of them Vox and Valentino

Vox: Valentino could you calm down you got like 20 girls already around you

Val: it's whatever I think I need 20 more maybe

Alastor was just away from the group drinking alcohol
