Rex patiently waited for Jessie to arrive.
He stayed behind the portal after making sure that Shadow wasn't directly in the line of sight from the portal. As soon as Jessie stepped into the portal, she could not see Rex, but Rex could see her. Like a shadow looming behind, he looked at Jessie, scanning the realm with neutral interest.
Silently, he approached her from behind.
As an expert assassin, she was attuned to any danger that might reach her.
But behind her was a blind spot in her senses because of the portal's distortion. Tearing through space from the Primordial Meadow needed an immense amount of energy, and is only possible with the use of a Permit.
The combination of both created a constant discharge of energy that distorted the space.
Because of that, Rex's presence was simply covered by the distortion.
Jessie couldn't sense him.
To her surprise, two hands came from behind. One held the top of her head and the other her chin.
