Nice one. You're learning to intentionally, instead of unintentionally, troll.
Btw, my recollection is that Luke actually wasn't strained when Jacen and co. saw him, and there's no indication that Kaan was able to do it with greater ease. Luke himself has mused that he could mentally dominate crews of war cruisers waaaay before his prime. If Kaan could do this, he would've just done so to the Army of Light.
It's convenient that he didn't do this to the Jedi, isn't it? Brotherhood sith are weaklings.
