Tuck's link didn't work for me, so it's New X-Men #142. Shaw threatens Sabretooth with a psychic lobotomy and apologizes to Cyclops for the "telepathic rummage." I had read this issue last week, and remember wondering if Morrison just flubbed Sebas' powers. Reading it again in light of this convo, Shaw does mention that all of his dancers are telepathic, and he also strikes me as the kind of guy who would talk about his employees' feats as if they were his own.
