Xavier hadn't planned on fobbing all of his tasks on his colleagues, but it turns out that a baby esper with a power nearly-perfectly suited to doing rescues for the double dungeon break is worth dropping your previous responsibilities. DRT operatives need to have many virtues, and one of them is flexibility.
Xavier's lost some physical flexibility to the encroachment of old age, but his mental flexibility is better than ever. He knows what can be dropped and what absolutely cannot, and a guideless esper absolutely cannot be dropped for anything less than an imminent civilian. In some cases, not even then. He's heard rumors about what working with Gridshell is like, and he's secretly glad he doesn't have to deal with that particular bucket of broken bones waiting to happen.
