Don't you think he was auditioning, though? It's no coincidence to me that (in retrospect) his last several collections for Jil were so Dior (I've even heard rumors that LVMH was trying to get rid of Galliano prior to his meltdown, so it's not like there weren't whispers amongst industry insiders that the position would potentially be available in the near future). And honestly, if he could reproduce that same effect here as he did there, I'd be much happier with his work (my avatar still happens to be from the Jil Sander FW11 collection - I loved what he did at Jil).
It's beginning to seem like, to me, he took the job for a big pay-increase and for the fame it would afford. Not because the Dior heritage was truly calling his name.
