The next few days, Gideon 'trained' the others extensively to increase their pain tolerance in preparation for their breakthrough.
This decision actually ended up being a great one, because when the time for the breakthrough actually came, Victoria, Lisk and Nathan were actually able to deal with it, a lot better than Gideon did.
Naturally, the apin they went to was simply unparalleled and the training only gave them a small taste of what they had to endure, but it was enough. That and just like Gideon, they were able to pull through via willpower since they all had their own desires.
Gideon also went through some pain because of the bond between himself and Lisk. It wasn't fun, but he was able to power through and make sure nothing went wrong with the rest of them.
In the endz it was a complete success, and the three had now reached a level of strength that far exceeded anything they had obtained previously.
