Erika tightened her grip on the gun, wanting to aim at Adrian but their movements were too fast, making her unable to get a perfect aim. Whenever she would get an aim, Adrain would someone switch over and Ethan would be in that position.
Frustrated, Erika lowered the gun but couldn't stand and watched them fight each other like that. Ethan wasn't completely recovered and if Adrian hit him on the head again, his condition would only worsen and she didn't want that to happen at all.
Luckily for Ethan, Adrain's stabbed hand wasn't able to let him hit Ethan as much as he wanted, allowing the latter to vent his anger in him as much as he wanted.
In the middle of the fight, some of Adrain's men came and threatened to shoot Ethan if he didn't let go of their boss.
