Dimitris carried Rachel away, he had to run for his life or he risked getting caught in the crossfire but he confirmed that Jason was alive.
This was the positive in this encounter but he didn't have it in him to tell him about Glenn's death.
Then again, was this information even important, as he understood what this could mean on a fundamental level?
Jason was strong, growing exponentially to the point that he could kill these creatures with little to no difficulty.
Jason was the one that has been protecting the community and Dimitris couldn't believe Rachel's faith paid off.
He didn't believe he was alive, there was no reason for him to be alive and Dimitris wondered what he had been up to this past year.
He managed to gain distance but with the horsemen no longer a problem, they could move without much worry.
But Dimitris ran into someone he didn't expect to as his eyes caught a glimpse of him through his peripheral vision.
