At the end of Eureka Seven, Eureka and Renton came out of the Command Cluster, then Nirvash and some other Corals moved to another dimension to maintain Limit of Life. But Eureka and Renton no longer returned to their home i.e. Bellforest though their names are mentioned in the Thurston family chart along with Maurice, Maeter, and Linck as a part of Thurston family.
What actually happens to them? Did they abandon them?
Also there is no mention of Maurice, Maeter, and Linck in the sequel Eureka Seven AO.
