On characters’ whereabouts

This is lengthy, so hold on tight.

First of all, who is missing by the end of OS?

5 riders were reported missing, and they changed it to 4 once Violet was back. We can assume Imogen wasn't among the missinh and wasn't gone the whole night, as she's standing right there and yet they didn't correct the count to 3. So 4 it is!

We know one is Garrick and it is safe to assume Aaric and Bodhi are missing too. Is Xaden still considered a rider or has his status officially changed to venin? Could Pancheck be the fourth missing rider or was his presence in Draithus unknown?

Let's assume it's our four boys though.

First off, Bodhi. There are all kinds of theories out there about who is the "new brother" but aren't we overthinking this? If it was anyone but Bodhi why would Xaden leave Tyrrendor to Vi and tell Sgaeyl it's the only way? He had been training Bodhi and believed he was going to be a great duke. The only other explanation is Bodhi's death but I cannot believe that's what happened. And the argument that he was already like a brother to Xaden so he wouldn't have said "new brother" makes little sense to me. They were cousins not brothers, while having the same sage makes venin brothers, we leant it from Jack. Now whether Bodhi is with Xaden or with Berwyn or with both is a question I need answers to.

Moving on to Garrick. He still had one walk in him based on "even if I made it to Aretia, I'd never be strong enough to get back". As he couldn't bring more weapons for the wards, he clearly went elsewhere and couldn't come back. Where could he have been useful? I don't think he could be anywhere near Xaden, because he'd already left somewhere by the time X made the onyx storm. He's the one I'm most confused about. What are your theories?

Aaric. I think he's the one who took the 6 dragon eggs. With his precog powers and a secret correspondence with a priestess, I am wondering if he is also in contact with the queen of Unnbriel. She wanted 12 eggs in exchange for her army, but could he not have negotiated to 6 (one from each den) instead? Maybe due to his powers he can tell this deal is the only way and he plans to get the eggs back eventually. That's why he was flying away during the battle, to deliver. Thoughts?

Finally, Xaden. I would imagine him wanting to go to an isle with no magic but as he is newly an asim, can he even survive without channeling? Also, if I'm right, there is now turned Bodhi to worry about. What are even his options? I think Andarna altered his bond with Sgaeyl so she could stay and he could leave. That would explain the plot need for her quick return, as irids have this power. So X can't even fly, unless they dropped him off somewhere. Perhaps they're even doing so as Violet is talkinh to Brennan in the end. Alternatively, he followed Berwyn to wherever they have their venin headquarters, but I doubt it. Unless he's collecting info! I am ready for him to play double agent and convince everyone he's gone fully dark while secretly gathering intel to bring the venin down.

If you made it all the way to here, I appreciate you <3 Now I need your opinions!
