Liz is way more mature than Lucky right now. An end game of Liz and Lucky could work, but the show will have to take their time with it. What I love about Liz is that she, like Laura, is a grown up. Lucy has remained a teenager -- doing good work, but flitting from thing to thing not making long-term connections. Taking care of the world while ignoring is son.
Liz and Lucky can be the end game, but it needs to be done slowly, SHOWING Lucky start to grow up and put down roots and take care of business instead of flitting from place to place.
