Well, I don't really have much of a plan for actually finding where they've gone, especially since we won't be able to get any help from the Beseedrans (I had been entertaining an idea of going to the starport and seeing if we can find someone to help pilot the ship, at least).
Once we find where they are, though, I was thinking that we should make as quiet and stealthy an entrance as possible. We'll have to fight Jarko, I'm sure, and as Rianna's had bad luck with that so far I'd want to approach that fight with her having as little damage as possible. Finding a way to deactivate the droids would also be nice.
If you want to get at Roch, a confrontation with Jarko seems inevitable. Just keep in mind what you have learned about his fighting style and what he comes equipped with, though he may have more weapon yet and there is no easy way of dealing with any of them.
As for deactivating the droids... for Roch to have enslaved the entire robotic army to his command means that all the droids must follow a single transmitter code, like the battle droids of the Trade Federation. Roch seemed to issue commands via the little remote control box he keeps on his person.
And Palpatine thinks that they have probably gone to Beseedad, as the vast majority of Beseedra's population is there. No point in releasing a lethal virus if there is nobody around to infect.
Beseedad seems as likely a place as any to go, then.
And yeah, his fighting style seems to be along the lines of "hit as hard as possible". Rianna's speediness and skill can surely be used against that. And even through Ciira is weaponless at the moment, she can use the Force to try and keep him distracted so that Rianna can slip in and out for attacks.
We'll have to get that control box, though. Last thing we'd want is an army of droids attacking while trying to deal with Jarko and Roch.
Ciira says she will make her best efforts, though she wishes his weapons were not part of him. She cannot disarm him.
The flight to Beseedad is uneventful. When you arrive, you receive an automated message from the starport asking you to leave due to quarantine... not many come to Beseedra from without, but Roch does not want his experiment getting out before he is ready.
You set down on an uncovered section of an empty street.
