If you knock her our during The Last Harvest, there's a pocket secretary on her with a message from Cirpa. It says something like "you're Orlov's child, not mine" and mentions that Cirpa transferred Daria into Orlov's custody sometime after the initial treatment. This is probably how she got Titan. No idea why Orlov would give her Titan though.
