Fair, but given the lack of psionics opposing Xykon, one showing up just to trace his teleport would be roughly on the same level as Xykon going to the fortress - useless except it happening for the sake of it happening.
And that's where you are wrong! Just wait for Laurin, co-possessed by Thog (courtesy of the IFCC) and the Snarl (courtesy of the Snarl) to show and spice things up a tad!
