Jolie Jenkins not in Season 4's Opening?
Pretty Good Last Season of Liv & Maddie I'll say, pity it'll only be 15 episodes, compared to the others which had 20 or more. I find it nice that they'd have another season after the last Season 3 episode was initially filmed in a way to wrap up the series, which Benjamin King thought so, and left the cast, making L&M the 1st Live Action Disney Channel series to get a 4th season where someone leaves the cast and someone becomes a Main Cast Member. Good times in LA, pretty different from what I've known of it, a fairly well known city with lots of events. Seems that Karen, Joey and Parker had already started living with Dena when the season premiered after the Season 3 finale, so Liv & Maddie weren't surprised and already knew bout the incident. It was even nice to see Linda and Heather themselves for the first time, where they'd let Liv and Parker play a role in an episode of their show (I wonder what Parker's SP Friends would be thinking), and Liv had been able to reprise her role as Stephanie Einstein in "SING IT LOUDEEEEERRRRR". Now that is rare, a show being succeeded a few years after it wrapped up which hasn't happened much with real life shows, and it was nice of us to actually see what goes on in "SING IT LOUDEEEEERRRRRR", unlike Liv's previous show where no actual scenes from "SING IT LOOOOOUUUUUD" were actually shown in any episodes. Lets not forget that I can't believe Parker decided to build Parker Tunnels in LA as well, even under Dena's house, and without the help of the beetles which helped him construct the ones in Steven's Point (someone beat him too it, as there was architecture in those tunnels). I wouldn't be surprised if when the Rooneys return to Steven's Point, the SP Parker Tunnels will all be sealed/buried in.
As for the Intro, nice touch to reflect the new setting in LA, more appreciated than the Intro of the First 3 Seasons (I'm talking about what Maddie does at the start of the Intro in those seasons), and though it was nice to put Ruby in to make up for Pete not joining the others in LA, Dena surprisingly was not featured in the Intro, unless she's only a recurring character despite living in the same house as the others. I know, these Live Action Disney Channel shows have tended to keep the number of Main Cast Members in their Live Action shows the same in all seasons, though Shake it Up went from 7 Main Cast Members to 6 main cast members after Kenton Duty left the cast. Liv and Maddie as we know is a show where the Main Cast Members are the Main Characters immediate family/immediate household, which Dena is part of in the last season, but L&M's not been the first time where someone's surprisingly not been a Main Cast Member (in someone's personal opinion). The last episode I can guess will premiere in March, currently titled "End-A-Rooney", making Season 4 the only Season to not conclude in the NH Summer.
Between now and the rest of the series, we can expect there to be more fun times in LA, more familiar faces from the other seasons return, and have a nice way to wrap up the series, like Karen receiving news that their house in SP has finished being reconstructed, with a choice to remain in LA or return to SP (Liv & Maddie I think will remain to follow their dreams as Young Adults now no longer minding being away from friends and family).
