While Dan is on the battlefield, an Aura enchantment that somehow becomes an artifact in addition to its other types will also become an Equipment. Any of its abilities that refer to either "enchanted creature" or "equipped creature" refer to the creature it's currently attached to. It can be attached to other creatures using its equip ability. If you try to attach the Aura Equipment to a creature it can't legally be attached to, it remains where it is. If the creature it's attached to becomes an illegal permanent for it to enchant, the Aura Equipment will be put into its owner's graveyard as a state-based action.

The Doctor's companion ability allows you to have two commanders if one has the ability and the other is a legendary creature that is a Time Lord Doctor and has no other creature types. Creatures with the changeling ability, for example, can't be a second commander this way.
