I see where your coming from, I do.
For me, Paul is nothing, I don't think he's a very good actor and his personality bugs me.
On the controversy side, if Libby/Paul was to die, it'd wreak havoc!
(Well, it would with Ringo and Steph... But, meh. Steph's gonna be hated, and Ringo not close to people like, say, Mike? Toadie? Summer?).
Libby: Susan, Karl, Zeke, Rachel, Ben, Steph, Toadie, Lucas. Practically everyone she knows would be heartbroken!
Paul: Rebecca, Andrew, maybe Donna, Declan kinda... Not many people would be distraught! Toadie would be sad but cheering on the inside!
