Catbert

I made Revan a light sider and in the LS ending he lives.

Some spoilers- What happened to him? At the end of the storyline I picked for KOTOR1 he was alive in that republic vessel attacking the forge and he wasn't there in KOTOR2, so... what happened to him?

Well after I fix the droid and he calls me a jedi I can't even convince Tarn that I'm not one. What I went to read on walkthroughs says you should get a third talk option, but he always cuts me off that the second and runs off, even if I persuade him I'm not a jedi.
