the paradox is now clear, cobb and saito
in level 1 they are just in yusuf´s drugged mind
in level 2 they are just dreamed in arthur´s mind
in level 3 they are just in love in eames mind
in level 4 they are just in cobb's deceited mind
and then in limbo because they are drugged and in love (and also dreamed and deceited)
