After you catch Mewtwo you can find her back where it used to be before. The first thing she does after seeing you is throw a pokeball right at you, mistaking you for a pokemon.

After apologizing, she then tells you she's looking for Mewtwo and asks you about it. You tell her that you already catched it which pisses her off enough to battle you right there. After that she says the exact words seen in the pic and then throws pokeballs at you in an attemp to catch you, and after all that fails she leaves running while saying something like "Please think about it, okay?".

You can later fight her again in Cerulean City where she – again – tries to catch you while claiming she will never give up.

I'm not making this up. This is what actually happens.

Oh, oh… oh wow. Well then, I guess all those years of neglect on Gamefreak's part didn't do her mental health any favors. =V
