In the first episode of the finale, Toph cracks the joke "We will all understand if you break up with him over this.", referring to Sokka's horrible sand-sculpture of Suki. She seemed to have a semi-serious look on her face as she said this. This led me to believe there was supposed to be some subconscious intent on her part behind the sarcastic joke. With this in mind, I understand the sudden brief Tuko shipping as easily explained asl her subconscious reaction to the failed subconscious desire behind her joke. I would like to know whethericsson anybody else considers this interpetation to be valid, oe if everyone thinks she was just being sarcastic. (and how everyone else explains the sudden and brief direct Tuko shipping).
