Mackenzie really wants to be on this show, as a main player. Or get a spinoff. She’s doing a “well” job of it. Unlike most of the new wives (Miranda, Vee and Kristina over there making sensible choices!) Mackenzie’s doing her job at being the biggest train wreck possible. And she knows Larry and Jen will always pick up the pieces for Ryan. It’s really shitty for this baby and their other kid, to have Ryan for a “father,” with everything that entails, but Mackenzie knows they’ll never go without due to Jen and Larry. I think this was a calculated decision on her part. It’s also, theoretically, harder for Ryan to leave her, if he was “fixin’” to do that any time soon or in the future, since there will be two kids for everyone to bring up that he’s ditching.
Ryan and and Maci seem really fertile, despite “obstacles” - Ryan knocked Mackenzie up while addicted to opioids and while seemingly never watching to touch her and Maci despite her PCOS and did a doctor tell her she couldn’t have more kids? - I wonder how many kids they’d have now had they stayed together this whole time?
