Cool! And I was thinking he would find her after Cas and Iris go their separate ways for the night, since Atlas set her curfew at 10. If he approached them right away, Cas would just call security and have him arrested again ^^; His com device also acts as a panic button if he's in danger lol

Also, if Ethan and Iris are alone, it would give them time to talk and come up with a plan to kidnap Cas (since Iris wouldn't be out to assassinate him anymore), which would lead to the scene change to the poor districts of Aspiria.
