What is onion routing?

Routing is a fundamentally public activity. Core internet routers can see both where the packet is going and where it came from. Even if the contents are encrypted, in certain cases it is dangerous to even expose that two computers on the internet are communicating with each other. One solution is known as onion routing. In onion routing, the structure of the messages combined with clever encryption allow routers to only know the previous and next hops-​but not the source or the final destination.

Atlast I clearly understand the basics of onion routing!

[@sabotocki]

Ok so I understand the forward path of traffic but how does the destination know how to respond back to the source ip? Does the last hop ToR router receive the response and repackages it in multiple headers for the path back?
