When Darius left the others to get better so he would take down Aya, he was not trying to get himself caught in anything else. But then three minutes after he left their side, they were shaken up by the rumbling happening close to them.
When Theo got up, looked around, and was confused about a lot of things. One of them was that he was on the ground with Darius nowhere in sight. His memory was hazy, but then he could remember something a bit vague, and it was rather disturbing for him.
He could remember himself stabbing Darius with his spear, but he was not in any way sure that was the memory he wanted to see. He could see Darius pushing them away, fighting trying to get something done with them.
Darius was looking at them trying to make sure that there was nothing going to happen to them while they fought him.
