Tyler appeared in a large white room after forcing his way through the distorted space that was yet to recover from the force teleportation spell the ones that kidnapped Liz had used. There had been a bit of a time lag in his transfer here because he needed to destroy several layers of defenses along the way. Due to that, the person that had laid those defenses should already be aware of their destruction and thus, he expects to face a well-prepared enemy.
Although if that was all, there would be nothing for him to worry about as long as they don't grow cold feet and try to run away with Liz. It would be bad if they also tried to use her against him but he had a plan for that. He also couldn't approach this recklessly and needed to do his best in controlling his anger until he has confirmed Liz's safety.
