Black hole growth is an alien process and there is no intuitive analogy from our daily lives to help us understand it, but under such conditions a lot of interesting physics is going on. This contribution is an overview of some of the peculiarities of episodic black hole accretion, and goes into the effects this has on black hole growth and rotation. Near a rotating black hole the interaction of an accreting disk of gas with the frame dragging effect is discussed, and the consequences of these processes for astrophysics are also briefly covered.
