I did like Brock interaction with Olivia, especially the latter didn't get weirded out so much by the former woman loving antics, even the Lycanroc doesn't mind the two of them making the Z-move together, along with that big falling rock shaped like a heart.
I did like the part where Brock took care of Kangaskhan and its kid, and we saw Lillie & Lana being amazed, with glittering eyes, of Brock nursing skills, in which they got quickly weirded out when Brock continues to search Olivia.
I didn't like the part where Team Rocket interrupted the fight of Brock vs Olivia, but I guess they wanted to make sure that neither of them are going to lose in their own matches. Bewear sure came to rescue Team Rocket when they were about to lose.
And those hikers are annoying. Sure Brock's obsession with Olivia is crazy but since he came to visit Alola, that would be good for him to have a memorable souvenir instead of his face being covered by one of them in the picture.
Overall, good episode. I found it more creative than the last episode, which felt like a rehash of the 1st Misty & Brock cameo episode a year ago.
