With thanks to Henry Potts for the heads-up.
In advance of ARW's show in Ravinia tomorrow comes a new interview, and interestingly this time Trevor does admit that "Fragile" (aka "Fragile/Touch") was in fact composed for Agent X. He also hints that they may perform it within their three remaining dates, which would certainly be a nice thing (but I'm not counting on it).
