user223: When delegating for the first time there is a 2 ADA deposit being spent.
Is this 2 ADA ever returned? if yes when is it returned and how?

user4302: Yes it can be returned. 2 ADA is the current cost of registering your staking key on chain (this is to prevent sybil attacks). If and when you de-register your staking keys, the 2 ADA is returned to the original address it was sent from.
