The Soldier is Not Here. They are outside and listening in under a window, sitting in the snow, because they couldn't convince themselves to actually walk inside. Which means adding to the conversation is kind of... hard. Even when one has actual pertinent information to share, which they do.

They heard Jason in there, though. Jason knows Bruce. Jason might not mind breaking into that particular conversation.

Jason gets a ping on his tablet from "Soldier" that says, Spirits do have hierachy. The green-eyed ones are bosses and give out jobs and control the others. They hide from them if they don't want to do what the green-eyed ones want.
