"Keep your eye on the stocking."
Seth says this to Veronica the first time he teleports something for her after meeting her the same night. He has used this science to knock her socks off, but didn't know she was a journalist who is ready to write his story.
"I knew I should have changed the lock."
Veronica says this to Stathis who has let himself into her apartment to take a shower. The statement reveals how they were once together and he has yet to respect the boundaries created once their relationship finished.
"Something went wrong, Seth. When you went through something went wrong."
Veronica has to hit Seth over the head with the obvious statement that he is not who he was when he went into the telepod. He is being transformed, and he has become blinded by the idea of changing the world with this science.
