Inspired by @QuantumTwinkie's anagram puzzles, I have created my own anagram puzzle. It has $20$ lines. Some are easy, some are hard, but whoever can find them all will deserve the tick $\color{green}{\checkmark}$.

After @Kevorobin posted the first answer regarding the 16th line (below), I will provide a hint to make it easier.
- He called her a "_____ ______" when she said that her painting of the _____ ______ was actually art, pretending that it didn't exist. Considering what he said, it was quite ironic. Nonetheless, the painting wasn't finished; she had yet to paint the station.
