Since the episode's on, I'll try summarize it and I did make translations on the discussion thread "Arts and crafts". Also helps me pay attention and focus to the new episode during its airing.

After the cold opening and the title card, a girl shows up named Matsurika with all the paintings shown. After fade cut, Matsurika paints on the blank canvas and Satoshi-tachi run up to them. There's a picture of walking a narrow mountain trail, on a rock at evening with a Pokémon I couldn't see because I was distracted with writing this. Mamane looks at the picture of the starry sky. There's even a picture of the snowy mountains and another before that I didn't remember. Then, there's a picture of the gang as well. Bevenom distracts them and begins writing ambiguous strokes on the ground in blue symbolizing a lightning symbol which Matsurika then paints by herself. Then, they show Abribbon on Bevenom, Rotom dex also shows a picture of the lightning symbol drawn by Bevenom. A scene cut transition to the house with Kukui sitting at the screen. Video pictures also show thanks to Rotom of Bevenom drawing. Lusamine also speaks.

Bevenom also drew more things such as Nyabby and others. A shot with Pikachu and Bevenom on Ash's shoulder which Rotom takes a pic of. They then sleep near his legs and shorts while Satoshi's sleeping. Creepy cutscene occurs and Bevenom gets freaked out. It looks at the moon lit sky crying. During the day, the heroes' Pokémon play around while they're at the Pokémon school. Pictures of Pikachu and Bevenom shown on the drawing board. Bevenom recalls the nightmare from the night before as Satoshi tries to resolve its issue and investigate. Bevenom rushes to Satoshi's arm. Rotom captures a picture of a tear being drawn. Bevenom continues to cry in Satoshi's arm, cut to the Skull Gang. Long story short, they confront Matsurika with their unhinged conspiracies being planned. They try drawing something. And then my timed free program stops for several seconds making me miss some of it. But the Skull Gang attacks and Satoshi-tachi realize this mischief. Attacks involve Pikachu using Iron Tail on Yatoumori (IIRC at the time of writing this after the scene cut) while Bevenom distracts Dustdas and makes it faint. Matsurika detects its sadness. Back at the house, it appears to draw some sort of monster dragon which looks like some bat Pokémon with wings (maybe Airmd or something like that? I initially detected it as Kairyuu). The episode ends there.

No, he doesn't release Bevenom to its original home unlike what one of the users on the forum speculated its sadness was for.
