Spoiler
Perhaps it was in the delivery of the flashbacks; they were kind of just revealed without a narrator, which would have been nice to further reveal another character's persona like they did with Cyclonus (granted, finding a narrator would be hard as most of the Ark 1's crew is dead/missing/off planet). At first I thought the flashback was the Metrotitan's memories. Omega was present during 80% of those flashbacks whilst Dai Atlas was the only one who was there 100% of the time. Perhaps they could have placed the flashback as Omega's, who had later had some later conversations with Atlas, and discussed details of Nova's personality and crew? This would have justified Omega's trust and friendship with Atlas (almost Spotlight Omega?). However, even if that was not possible due to page limits, I would have liked more timeline with Noble Nova before his eyes suddenly turn red.
The annual was very good, more enjoyable by any one other RID issues, but the present-day story did not keep me on the edge of my seat the way the MTMTE annual did.
