Alex was about to make a tactical retreat, so he slowly backed away but to his surprise Niel blocked his escape route. He wasn't expecting this kind of betrayal from a comrade.
"What are you doing Niel?!" Alex who was always calm and collected was a bit flustered by this unexpected move. Ever since he returned from the battlefield, Alex has been affected too much by his emotions, and the one who triggered this response the most was Rachel.
As long as the matter was about Rachel Alex felt a bit lost. He was sure that he was feeling this way because he was afraid of failing the mission... But there were times that he thought that there was something more going on. He couldn't understand it, but since it was affecting the efficiency of the mission Alex decided to not think too much about it.
