Yes they were stucked there, but Neal comes from our land to wonderland. We know it is not possibiliy to jump from magical world to non magical world, but the other way around it could be easier, because the hat of Jefferson couldn’t jump to our wolrd, but he was able to ue his hat from our world to ET (the poisened apple). That would mean that it is easier to go the other way. Example: We now that the magic bean was in ET not any longer possibile to get, but maybe there are some in our world and he found some and go to Wonderland.
