Warning: Major spoilers ahead

After being dumped for lying about his family, Malcolm is still desperately calling Tristan but she refuses to talk. So, he takes things to the next level and calls in reinforcements, making Leah go to her house.

When Leah comes out, he neurotically demands to know everything she said, but Leah simply says Tristan doesn’t want to talk to him. Instead, Leah encourages him to go to Hal and Lois’s anniversary party so they can be a family, but he refuses, saying he’s protecting her. He then furiously rants at himself in the car, saying he thinks Tristan is the one.

At the microdosing office, Hal begins to trip and hallucinate. Soon, he’s naked on the floor as his friends watch on.

Hal interacts with alternate versions of himself during his trip, including a successful version, and a goth version. “Perfect Hal” analyses him, and he admits that raising his kids was his purpose, and as each of them moved out and didn’t need him as much, he’s felt obsolete.

Perfect Hal urges him to think about his own needs as much as his family. He says he “needs to put his own mask on first before helping others”. He advises him to cut them off and do his own thing – potentially even killing them. Hal’s horrified and he realises that he’s not perfect, he’s Evil Hal.

Hal throttles and beats his inner evil self, though it does little to affect him. Evil Hal tells him he needs to grow up and accept him, because he’s been inside for years. Hal tells Evil Hal he loves him, which freaks him out, but he says there’s nothing about him that’s scary, but hiding him away made him seem that way. The more niceness he shares, the smaller Evil Hall gets, turning into a bubble he then absorbs.

A Buddha then appears, giving him an animal partner – to Hal’s disappointment it’s a hairless rat – which leads him to a closet. Following the rat down a long hallway, they arrive at a cake on a table. He cuts a slice, but it just becomes a full cake again, which excites him. He cuts lots of pieces but it doesn’t get any smaller. He says he “gets it now” and celebrates in victory.

Back at Malcolm’s house, Leah is messaging Jason, the boy from her class, and they start flirting, but they’re interrupted by Malcolm who is still trying to work through his break up. He suggests spending more time with Leah and suggests they spend time at his cherished childhood pizza chain restaurant, and she accepts.

As Leah and Malcolm head on their father-daughter day out, Leah blindsides him by knocking him out and throwing him into the back of his car. She’s in cahoots with Tristan, and the pair drive off.

Leah calls Lois to let her know that they’re on their way to the party and can make it after all. Malcolm wakes up in the backseat and tells them that they shouldn’t be doing it. Leah tells him he’s the one with the problem. He finally admits she’s right and he was sorry.

As they head to the party, Tristan shares that, 12 years ago, she was arrested for attempted murder after her mum’s abusive ex kicked her door down and she shot him in the crotch. She was arrested because the man was friends with cops, who believed him. While her records are sealed, she earned the nickname ‘Titty Titty Bang Bang’ in the papers – because she was naked during the attack.

Meanwhile at the house, Reese vows revenge on Kelly for ruining his YouTube channel. To retaliate, he’s trashed Kelly’s principal’s office and pinned it on them.

Kelly promptly gets their own back by contacting the IRS and reporting Reese’s undeclared earnings from the online videos. Now it’s back to his turn to come up with something to take her down.

Francis becomes fixated on sending Piama’s pregnancy up his mother’s priority list by any means necessary. He starts by giving Lois $1,000 to go towards the party, which she immediately squanders on an unnecessary upgrade to the speaker system, which infuriates him. She tells him to stop worrying about the list, and he finally softens when he spots she bought baby booties while running all the errands, and he realises she does actually care.

That night, Lois realises she bought the wrong kind of candles and is shaving them into her preferred shape. Panicking about the party, she needs reassurance from the family that they know what they’re doing tomorrow – but with Hal still AWOL, there’s only so much positivity they can send her way.

On the morning of the party, Abe confirms Hal’s whereabouts, and Lois picks him up, having been dumped outside and still slightly tripping. She’s furious with him for doing drugs, but he’s got a new lease of life.

As she drives them both home, she’s multi-tasking – caught up on the phone and still sorting out arrangements. With her attention distracted from the road, they get T-boned at a junction.

Hank is fine – but Lois isn’t.
