Lisa and Lee's relationship...is like Han Solo and Lando's relationship...remember in Star Wars when Lando betrayed Han to serve his own purposes? that is something Lisa would do to Lee...remember when Han forgave Lando...and they became buds again...and Han and Lando fought that monster at Jabba's lair? Lee would do the same....Lisa...after betraying Lee...would feel bad about it...like Lando did. If Lee would have died...after Lisa was rooting for Tess...Lisa would be happy she gets Lee's money...down the road...she'd feel bad Lee was gone.
