I’m thinking I agree with you. Although we seem to be led to believe that SB is over FTL which we saw being taken apart piece by piece when the Curse was enacted, so I believe a destoyed FTL may be under SB, but Wonderland, that could definitely be another realm all together, and wouldn’t it be funny/odd if say Kathryn fell down a hole in the SB woods and found not pieces of FTL, but Wonderland instead:)
