I had a good feeling Sirzechs and the others were still alive and kicking, though I didn't think they would be actually fighting Trihexa in there.

The wording I've seen describing what they did seemed like the seal was gonna continue where God's seals did for a while longer while weakening the beast so Trihexa would be weak enough to destroy after it was freed again.

Question is will we see Trihexa actually fall by the series' end? Correct me if I'm wrong, but from what I've read I think EX implied they're still in there even if they're no longer fighting.
