Finished all previous episodes a long time ago and wondering I can get the Mega Stone for Gyarados now.

Item Guide says it's in the GlassStation Workshop's puzzle. But I've completed that puzzle already thus Espeon and Glaceon aren't available anymore and wonder if I can still get or am I really locked out...
