You get to see Bastila in a brief scene with Carth Onasi, and both of them express how they’re wondering where Revan is. Other than that, Bastila isn’t mentioned by name in any of the dialogues in the game. This is why less is known about her than Revan as Revan’s story gets expanded on quite extensively in the game. Bastila doesn’t get involved with the battles in the galaxy at this time as she’s raising her son in secret while avoiding the Sith Triumvirate who were hunting all the Jedi down.
