I can attest that recruting her as a good character in Act 2 works wonders, cause that's what i did by cheating the game's variables through the unlocked console command...lol.
Am I understanding correctly that you convinced the game that Mithara was still alive and then met her normally in the tower? If so, can you please share the details? I would LOVE to do the same.

I think the developers were shocked at how popular the character is, that they decided to at least give her some extra dialogue and started referring to her as a companion.
