To get multiple followers etc.2
You have to have a follower follow you such as vilkas from tbe companions or anyother follower that is not a hireling. You also need to be in the dark brotherhood and have completed all contracts and missions for brotherhood.(when your in the 2nd sanctuary)-not to spoil it. But anyways once you have your follower follow you into the sanctuary, find an initiate. Then after you find an initiate, talk to your follower and dismiss him/her, quickly then turn to the initiate and tell them to follow you, after that quickly turn back to the follower you brought with you and talk to them. If done correctly it should give the option to tell them to follow. And then you have both also you can get a dog in Markarath for 500gold at the stables.
