Hm, that’s an interesting one. Release order was Bad Batch > Martez > Finale, but production and chronological was Martez > Bad Batch > Finale as you say. I’m tending towards BB > M > F because Bad Batch isn’t really important to the rolling plot (beyond setting up the spinoff), and because the Mauldalore elements of Martez Sisters can serve to build anticipation for the forthcoming finale. You could possibly ignore it - maybe Padmé wasn’t aware that Anakin’s been local recently, and an implicit time gap between episodes is fine. But I agree that the scene of Anakin sensing Ahsoka is worth preserving.
There’s a third option, which might emerge after the Bad Batch show kicks off, and that’s turning the Bad Batch episodes of The Clone Wars into episode zero of the Bad Batch TV show (flashing back to pre-rise of Empire). Though the obvious negative would be losing the impact of the good Anakin/Padmé scenes and the hints Obi-Wan knows, which I think is additive to the Clone Wars finale and RotS.
I like your idea for the title, Delpheas. I think you’re right that the emphasis should be on Anakin’s knighting since that’s the one main takeaway from the episode along with Ventress’ existence. Could maybe go with KNIGHT AND ASSASSIN though that’s a bit bland. The other option I’d thought of, since Tartakovsky’s a bit more light, is going a bit cheeky with it. Something like BEGUN, THE CLONE WAR HAS. But I don’t think that’s quite right either.
Speaking of episode titles, I’m now thinking about the Holocron arc, and had been considering emphasising Cad Bane (because he’s so much fun), with either CAD BANE: BOUNTY HUNTER (because that tells the new viewer we’re getting some bounty hunter fun) or the even schlockier CAD BANE AND THE HOLOCRON HEIST, which is just pulpy fun.
