This week’s episode of “The Flash” featured a return to Earth-2 and an epic showdown between Barry and a gorilla king named Solovar. Barry and Team Flash traveled to Earth-2 after Jesse showed up on Earth-1 declaring that Grodd had taken her father captive. Harry Wells was lured to Gorilla City through a highly intelligent algorithmic message -- unfortunately all of his team was killed and he was kidnapped. While Barry, Caitlin, Julian, and Cisco traveled to Earth-2 to find Harry, Iris, Joe, Wally, and Jesse stayed behind to safeguard Central City. This created an opportunity for Wally and Jesse to address their feelings for one another. While the end of episode seemed to conclude the “Attack on Gorilla City” storyline, it actually set up an Earth-1 gorilla invasion that will make for a pretty epic hour of television next week.

In Grodd We Trust

Picking up from the last episode of "The Flash," Jesse arrived from Earth-2 to recruit the help of Team Flash to save her dad. Barry decided to go because he genuinely wanted to save Harry and because he wanted to change another headline for Iris. The headline ominously said that Central City was finally recovering from a gorilla attack. Barry saw going to Earth-2 as an opportunity to keep Grodd from coming to Earth-1, but that's not how everything would play out. Julian, Caitlin, and Cisco all decided to go with Barry -- Julian not only brought a gun for protection but dressed very appropriately like Indiana Jones. At first Julian said the he wanted to go to another dimension for "science," but later he did reveal that he wanted to protect Caitlin.

When Team Flash arrived on Earth-2 they wandered into a trap that was left for them by Grodd. Grodd then imprisoned them inside a room where neither Barry nor Cisco could use their powers. When Harry (Earth-2 Wells) showed up inside the prison they were elated to see their friend -- what they didn't realize was that Grodd was using Harry to communicate with them outside of his telepathy. Grodd then gave Barry an ultimatum: fight the leader of the gorillas -- Solovar -- to escape, or die on Earth-2. Barry very reluctantly agreed to the proposition after Solovar confronted him inside the prison. This kicked off an epic Gorilla City fight-to-the-death gladiator-style battle: The Flash vs. Solovar. Barry tried to use his speed punches and speed lighting, but Solovar was too strong and too smart for him. It wasn't until he used a Reverse Flash hand phase that he knocked Solovar to the ground and was declared the winner. Barry chose not to kill Solovar and instead showed him mercy.

This show of weakness by Solovar gave Grodd the opportunity to stage a coup and become the new leader of the Earth-2 gorillas. Caitlin then had to pretend to kill Barry so that Grodd would drag him out of his cage, so Barry would rescue the rest of the team. While the team was able to return safely to Earth-1, they did not leave without scars. Barry was injured pretty badly from the gladiator death match and Harry was recovering from Grodd's mental manipulation and telepathic control of his brain.

Speedforce-Crossed Lovers

While Team Flash was off galavanting around Earth-2 (and trying not to die,) Team Kid Flashes were left to defend Central City. When Jesse left at the beginning of the season, she had speed powers but Wally didn't. After learning that Wally had become a speedster, Jesse felt like he didn't need her anymore. After seeing Wally showboat in front of two tied up baddies and a crowd full of onlookers, Jesse pulled away to be alone. It wasn't until after a heart-to-heart with HR Wells that she realized she was still important to Wally. He confessed to her that his powers could never make him as complete as she did. This confession prompted Jesse to ask Wally what would happen in their relationship if she decided to stay on Earth-1 when her father returned. He kissed her right away, which was the answer she was looking for. When Harry Wells did return at the end of the episode, Jesse didn't tell him that she was considering a move to Earth-1. That will likely come next week.

Changing the Future

The episode concluded with a few different romantic storylines. Barry and Iris snuggled up on the couch, happy that one more headline had been erased from the "future board." Barry was also happy that he could "change the future without changing himself," which he was tempted to do when he had the opportunity to kill Solovar but instead showed mercy. Wally and Jesse shared a kiss and the excitement of possibly living on the same Earth together. Julian and Caitlin agreed to grab dinner, even though Caitlin told him to be afraid of her. It seemed like love was in the air for everyone except Cisco, who is going to have a rival Vibe-ster on his hands next week. The final moment of the episode showed Grodd ready to lead his army to attack Central City with the help of Gypsy. Looks like that headline is going to be coming true after all.

Next week during "Attack on Central City," Grodd and his army of intelligent gorillas will make their way to Earth-1. All of the speedsters -- Flash, Kid Flash, and Jesse Quick -- will unite to stop Grodd's army from destroying the entire city. How will Cisco react to Gypsy's betrayal?
