What we need, imo, is a male companion who has /no/ attachment to the female character in the TARDIS. Captain Jack's brief TARDIS run was absolutely fantastic and one of the best-- when the male companion is basically an extension of the female companion in that there is a romantic angle between them, they feel like less of their own character, honestly.
If this "Danny Pink" has a romantic angle with Clara, it'll likely be a bit frustrating, as I'd rather him be 1. someone for the Doctor to be 'bros' with for a while, a la Jamie, Jack, or Harry, or 2. a villain, hidden in plain sight. They need to spin the companion dynamic in a new and refreshing way this time around.
