Just thought it warrants a mention that we don't know for sure that Tobias' human morph never aged. There's nothing said about it in the series, and Applegrant said a few months back that they'd never even considered the whole situation. So while it would seem that his morph would be forever 13, there's nothing that could have prevented it somehow ageing normally - or given the unusual circumstances of how it was acquired, I could easily buy Ellimist intervention that ensures his morph age is "up to date", so to speak.
