Sojourn is in some position of authority in Overwatch, and she offers a set of instructions in the new teaser. “Commander Morrison. I have a proposal. We’re going at catching Doomfist the wrong way. He’s clean, but his accountant, Maximilien? Follow the money and you’ll find the dirt you need. I know you’re worried about sending the strike team out again after what happened with Reinhardt. But I’ve been working with them and I know they’re ready.”
The remainder of the message pretty much tells us who the playable roster will be for the event. “I’m putting Tracer in charge, with Mercy, Winston, and Genji in support. She’s grown as a leader since the King’s Row mission, and I know you’ll agree. Call me back when you get this. And commander – trust me, they’ll get it done. Sojourn out.”
