Rex was surprised when he saw that he was standing on his own feet.
It weirded him out since he was mounting Delta earlier, right after the fight with the mutated falcon, but now he was coming out alone without Delta by his side. He tried to blink his eyes a couple of times to make sure he was not in some sort of mind control.
But he saw that the situation was still the same.
Delta was not with him, the two somehow got separated as they exited the dominion.
"I came out with her, I'm sure of it," Rex uttered, as confused as Delta was.
Just then—however—when the two were utterly confused Delta slowly walked out of the fog and widened her eyes in surprise when she saw Rex was in front of her. She also reacted the same as Rex when she got out.
Seeing her coming out, Rex immediately went to check on her, "Delta, where were you?"
Rawr! Rawr!
"Huh? You also thought that I was on you?" Rex frowned, the situation was weird.
