Just after the call, Bryan slammed the phone on the table in his hotel room. This was getting more and more annoying for him. The police won't give him leave and Emily was on his back and it made him feel the pressure.
He knew well enough that the lady had every right to be angry at him and order him around after all, he shot her only sister in the head years ago. She was actually forgiving enough to let him go with the order to find Zurich and Malcolm so she could end the madness.
Bryan would've done this even without her asking him to do it but then he felt he owed her this much but now the police seemed to be his breaking point. He couldn't just go against them although he knew that he had the advantage over them.
