Yesterday when the whole debate about Zuzu happened and Tina was called into the secret room, I thought what a relationship both Shalin and Tina have. As one thing which striked me was when Tina was inside and everyone was talking outside about her Shalin said something like 'I thought it was an imaginary friend'. I am sorry but if a friend thinks I have made up friends then they are 1. not trusting me and just there with me out of necessity or 2. think I am mentally unstable. Also his 'baby girl' comment was inappropriate if he really likes her he should be fine with however she is and not make fun of her being in her own world. Then clearly they are not meant to be for each other.
I am not a TIna fan at all but I always thought Tina plays with Shalin, now I am not too sure anymore.
