I'm surprised everyone is so convinced that Kevin's kids were 10 or under. I thought they looked 12 or over. I looked up the actors and, while there are no ages listed for them on IMDb, the summary for Preston Oliver (the boy who played Kevin's son) says be became interested in acting in 5th grade. Since he had acting credits going back to early 2019, he is likely at least 12 unless he 1) skipped grades and 2) got primetime guest roles immediately upon having the notion he wanted to act.
As for how Jack might be "on his way," it is possible that the they meant he and Hailey (ugh, Hailey and Hope) are on the way. Hailey could end up being older than Jack. Kate was looking at images of kids who were already older toddlers. So they might adopt a kid who is 3 or 4, rather than an infant.
I like both Randall and Kevin. I liked them both from the start and was never a keen on Randall as other in S1 since I thought he was a right ASS to just move his father into his family's home without discussion. And I always thought there was more to Kevin than we were shown in the beginning.
My take is that Randall went harder and deeper and that Kevin lashed out with the meanest thing he had in the recesses of cruelest feelings in retaliation. I also think that telling a sibling your parent died ashamed of them is more painful and insidious than telling one you wish they'd never been born or adopted (though I acknowledge that adoption carries some additional potential insecurities to wound). Sticking a knife in about a dead parent is something that sibling cannot truly resolve since the parent is gone.
Also, it wasn't true.
I saw above someone said Kevin couldn't even care for himself as a self-involved drunk until he go sober. But I don't recall that he was an addict before his knee injury. As for being able to care for himself, he was shallow and immature, but he was working and taking care of his responsibilities. Yes, he had an assistant (in Kate), but that doesn't mean he was a total feckless fuckwit. And we've seen a lot of growth from him over the last three years.
I can see why Kevin leaving and apparently living a mostly charmed (and,to Randall's mind, uneared) life would rankle Randall as the kid who stayed. But, damn, Randall cannot deal with Kevin being successful. That shit about following in his and Jack's shadows was UGLY.
Add me to the list of people who like Madison. I thought she was the best option from this year for the baby momma. I don't know if she is who he ends up married to, but I would like to see them build a real relationship. I'm a sucker for unlooked for love. In either case, I don't want it to be Sophie. There is WAAAAAY too much water under that bridge.
Good bless Beth. She was lovely as always both in person and manner. I loved her repeated escapes from the minefield every time Rebecca's care came up. Also, her knowing ushering everyone out when she realize the Pearson Bros were about to blow. I also appreciate that she was clear with Randall that she thought his methods were shitty, but she remained his partner and supported him, if not his actions.
