Q27 (by my counting)
Is there a definitive answer to the argument about Summoners / Synthesists / Eidolons and the "Enlarge/Reduce" chain of spells?

As I read it:
Eidolons can share 'self' spells as if they were not Outsiders, but Enlarge is a 'target' spell.
Synthesists count as Outsiders, so can't be Enlarged (and, enlarging the Synthesist inside the Eidolon has very little effect).
