Splitting the party is bad if each player is controlling one character. But on the other hand, if you somehow end up with players controlling more than one character (leaving aside how you end up in this state), then splitting into groups such that each group only has one character per player starts to sound sensible.
But as with anything, when GMing, beware with utmost caution anything that sounds sensible.
[Reminder: Our guest commentators have not seen Rogue One. Part of the fun is seeing how their untainted impressions re-interpret the movie through the lens of our comic.]
Poor Jim got so carried away in his (truly) brilliant plan that he forgot the most important detail: how his last character died.
Having a water planet be an actual gigantic bucket of water sounds like something Douglas Adams would have come up with. Either that or a Horton Hears a Who-type thing.
In the end though, I think Bria/Jim's on the right track. Why scan from a distance at this point when you could just fly there and probably get some better scans, and then be able to reach it faster after finding it? Also it's probably best to keep giving Bria action. She seems like the type to get cabin fever pretty quickly, so staying holed up in a Rebel base would be a bad idea for her.
I think I have finally managed to predict something in this comic. My thoughts about the momentum transfer from the planet to the water, and the idea of raiding the secret data facility, both show up.
Just remember: Jim plays this game to turn his mind off. He sure is successful.
Bria: Here's what we should do. Bail can handle Polis Massa on his own.
Bria: To find Toprawa, we fly to Kamino. When they shipped the water off-world, they'd be transferring momentum.
Bria: We compare its orbit with navigational records and calculate the difference vector. Follow that, and we'll hit the water.
General Draven: That's never going to work...
Bria: That's what's so good about it! We just need the shipping schedules, launch locations, and cargo manifests.
General Draven: For a top secret Imperial operation?
Bria: Sure! We raid the Imperial data facility to get them!
Tynnra Pamlo: You mean the one on Toprawa?
Chirrut: I think there's a hole in your bucket, Jim.
Bria: No, they'd need something bigger than a bucket.
