After Jason had created an opportunity to break the ice and get comfortable with the other Celestias, he spent his time sparring with them, once in a while.
This helped him to improve various aspects of his combat prowess, allowing him to be less dependent on the Soul fusion which he had always used in the past.
There was a dull ache in his heart because of the loss of his soulbonds, but they were just separated from him, and could always reunite.
This was something Jason was confident of, and his heart was telling him that they were safe and sound.
Maybe some of them were creating trouble, but that was something beyond his control.
In the end, they had been teleported together, and Jason was sure that his soulbonds wouldn't abandon each other, even if the connection they had to one another was cut off.
He connected all of them with one another.
Yet, right now, the bond between him and the soulbounds was severed.
