In the room next door, Jesse is switching between pacing and sitting on the sofa.
He can't believe that he was unable to stay away. What is wrong with him? He watched Oni and Robert in the restaurant and followed them to the nightclub. Part of him hoped that Oni will check his location and see that he is right there, but she didn't. Does she really not care where he is? He was supposed to be on a mission. What if he was captured?
After that, Jesse followed them to the bank of The Main river, and he saw that Robert tried more than once to put his arm around Oni's shoulders. Luckily, the guy is a coward, or Jesse would snap that arm in two!
