As of A6A6I5 everybody is on the victory platform getting ready for 4 x Showdown. Is it before or after Caliborn's Masterpiece? When exactly are the Betas swallowed by the Treasure Juju? If we're not at that point in time yet, is it likely that A6A7 will go on forever so that there's significant gap between capturing and releasing betas from said juju? (so it's not anticlimatic thing like 5 panel gap, but atm everything is possible)

Before the masterpiece, and they’ll be trapped in the near future.

And it’s most likely that (or at least I believe) they’ll be released before they’re captured, from the over all homestuck timeline. Meenah’s army has the juju and they’re going to fight LE right now. Presumably when the juju meets English the kids will be released.
