*** LEO AND JENNA ROUTE SPOILERS ***
No offense but how can some readers miss the point of Leo's route so badly? It read like a reality check on how dangerous sticking around in toxic relationships, staying with a mentally ill person and not moving on can be. Echo is not a happy dating sim where years' worth of emotional and mental issues can be fixed with love. If you want that, then look elsewhere because you'll get your heart broken again and again.
"Leo really loves Chase (although somewhat obsessive)"
Understatement of the century! It's not something cute like plain ol' love, Leo has a psychotic obsession. Yes, people want to blame Echo (the town) but both in Leo's and Jenna's route, the game makes it crystal clear that Leo had all those issues (like a laundry list of common abusive/toxic traits) but Echo just amplified them. Leo is bound to stay toxic even if he and Chase left Echo- Leo's dismissive of psychiatric care so forget therapy or couples counseling. Leo has proper mental issues that lurve will not fix, in fact, him clinging on "love" made him worse.
