About everybody that survived really... Except for Canderous who decided to follow Revan his orders and rebuild the Mandelorian clans, however even he was on the look out for Revan. Mission and Zaalbar are harder to know about, Kotor II never even mentioned them... However if they were alive its very likely that they would have worked with Carth and Bastila trying to find Revan, if Zaalbar was the only one alive he would have probably been killed since the events in Kotor. He wouldn't have lasted five minutes without trying to kill Sith after Revan left.
When did she ever say that?
And if she did say that, its obviously wrong. Canderous kept a watchful eye out for every rumour about him, T3 was acting on his orders so he wasn't looking for him, but HK was when he was restored. Carth and Bastila were both looking for him, and all the others well its unknown if they are even alive. However if they would be alive they were searching for him. At least Juhani would be, Jolee I don't know I wouldn't see it past him to stick with his friends and try to find out what the hell happened.
Zaalbar owns him and would definitly try to follow him and Mission would follow Zaalbar, everybody was looking for him really.
