Ves brought Isobel back to the same compound where he and his family resided on Yernstall IV.
There was no need to bring her to the Tarrasque right away. In principle, Ves could even let her remain at the recovery facility for a few more weeks until the Bluejay Fleet was ready to depart to the Rubarthan Pact.
However, Ves grew concerned about the RA's attempt to win her over. The more Isobel remained in the custody of the mechers, the greater the possibility that she might actually choose to defect to their side.
Ves liked to think that Saint Isobel possessed too much loyalty to the Larkinson Clan to ever contemplate such a choice, but nothing was impossible. It was best to remove the possibility entirely by keeping Isobel closer to him than the mechers.
This decision burdened him with keeping Saint Isobel occupied. She needed to spend her time wisely in order to start off with the best possible footing once she was finally able to get back into action.
