Alex waited for Whisker to return before he attacked the seal. Just in case he failed and ended up injuring himself somehow, he would need Whisker to take care of him.
Whisker also needed to return in order to enter his Soul Space if he did succeed and handle the things inside. Without Whisker, things would be a little harder to take care of inside.
Whisker returned two weeks later, during which period Alex prepared as much as he possibly could.
When he told Whisker that he was ready, Whisker was more than happy to hear that.
"Really, brother? Can you break the seal?" Whisker asked.
"I hope so," Alex said. "I have trained without a single break for the past 3 years. At the very least, I should be able to make a big impact on the seal."
Whisker nodded. "What should I do?" he asked.
"Nothing. Just sit around and wait. If everything goes well, I'll be able to send you back to my Soul Space. If not, I will have passed out, in which case you will still be needed."
