Lucas is most definitely not moving on from anything. He's painfully stuck with no way out because being a tranny he can't take the L or exercise common sense or work a job. But the difference with Elliot is significant. Elliot also is incapable of moving on, spending 7 years obsessing over a webforum and literally killing trans people by not using his money and power to help trans folk out. Sad. He's increasingly hiding his plans to commit crimes, if he goes dark, it just means he's planning another way to attack. He's forever escalating because he can't let go until either he burns or the world does. He's a lunatic. Lucas can't escalate, or won't, he's increasingly sinking deeper into a spiral of pain, painkiller abuse, depression, self hate, despair and lethargy. He will trickle out and while he won't let it go, it will just eat at him as he fades away.
