I can't even make sense of that one really.
Distractions are all very well and good, and may help, but the important bit is that you are still one 'speeder move' away from the starport. You MUST get the guys there quickly and no amount of messing around will prevent that primary need. They cannot make it on foot.
Barricading is totally impractical both because you cannot hold and because Galder's not even coming that way... and he wouldn't be useful even if he was.

The danger is imminent, Relle, as the starport is being sealed off. Xavier's ship is still there as well btw.
