Emery had his reasons for not leaving this place with Klea and the others. Even though it related mostly to Silva, it wasn't for the reason that Klea thought of.
Just like what the supreme magus had warned him about the drawbacks of his actions and Emery knew he was on borrowed time. Because of that, he had to make sure that he did as much as he could while he still could before eventually facing the serious repercussions – whatever they are – after.
Emery exhaled a relieved sigh when he saw the portal closing in front of him.
Now that the acolytes had been secured, the next thing he should do was to save Silva, someone who had done so much for him, and then hopefully he can also find Eshoo, one he felt responsible for leaving behind.
