Olivia was not happy about the fact that every now and then, she had to remain behind when Henry went to fight. She was his second in command, and she was supposed to be his support. But, now, she was completely useless in some fights.
For example, during the time that Henry was fighting against the clone, she was not there as well. For that reason, she had decided to go against the order that Henry had given for them to retreat back to the territory. And that was the reason why she had stayed around, and after 30 minutes went by, she decided to make a move.
It seemed that what she had planned had actually paid off. Otherwise, Henry would have perhaps been killed. And now, just dealing with the scorpion was giving them a lot of problem although there were three of them combined.
