Teleportation Problem?

Lets say you have 2 Teleportation pods, one being Pod A and another being Pod B. Pod A is smaller then Pod B so it can fit in Pod B. What ever is in Pod B Teleports to Pod A. So let's say we put Pod A into Pod B and Teleport Pod A to Pod A... Where will Pod A go if it teleports to itself? Try to Answer, sorry it is a little confusing! =/
