Very interesting. WENG-CHIANG. Could this be an anagram of some sort?
The DW episode makes me think that its not just a coincidence... because of the Superwholock stuff.
Maybe this is to signify that something will change in the next season? Because Baker didn't have his signature, normal apparel...
I feel like the anagram could get us somewhere though.
