The \spy command is postponed until the end of the current scope (the tikzpicture in your case), because it needs to know the whole picture.

By putting the picture in a scope environment and adding the commands to write into the magnified part after it, the latter will be visible.

Replace

\begin{tikzpicture}[x=3cm, y=3cm,spy using overlaysshadow={magnification=2,connect spies}]

with

\begin{tikzpicture}[x=3cm, y=3cm]
\begin{scope}[spy using overlaysshadow={magnification=2,connect spies}]

and at the end replace

\spy[size=10cm] on (0.25,0.25) in node at (3.33,-1.66);

\node[below,ultra thick] at (3.33,-1.66) {$T_A$};
\end{tikzpicture}

with

\spy[size=10cm] on (0.25,0.25) in node at (3.33,-1.66);
\end{scope}    
\node[below,ultra thick] at (3.33,-1.66) {$T_A$};
\end{tikzpicture}
