Theo dialed the number Joshua had given Captain during the exchange of contact information in the garage. Still nervous, he kept an eye out while the phone rang.
Speaking a little louder than he was comfortable with Theo said "Hello, Joshua. It's Theo. Listen, I need to talk to you as Sentinel. Is there somewhere I can meet you?"
"I will, I promise. Believe me, I'd much rather see what's up with you than be dealing with this situation. I'll call you back soon, Theo." If that's all, he hangs up.
