Sorry for hooking in, but when/where do you meet Carth? I only saw him on Dantooine, when the Disciple contacted him (I was playing LS male). I assumed that afterwards you get contacted, but I didn't.
And the Harbinger was destroyed on Peragus already, wasn't it?
As for the ending: I was totally confused. I saw Hanharr and Mira (ok, Hanharr was told to hunt Mira down by Kreia on Goto's yacht, so that's understandable), but at least Mira must have been following you or been in your ship. But where the hell did she go after defeating Hanharr???
In addition to that Goto came, and the remote, and you see BaoDur commanding the remote (don't remember if the first cutscene where he send the remote showed him as a hologram though, the 2nd one does for sure)... where do they all come from?
