Emerald/Mercury fight Team CFVY and pretty much stomped Coco/Yatsuhashi. It was nice seeing that team more, but they were pretty much fodder for plot advancement. Coco pretty much was shooting everywhere and missing while Yatsuhashi's big ass sword was too slow to keep up with Mercury. Mercury even soloed both Coco and Yatsuhashi for a bit. Emerald might have some shapeshifting power since she disguised herself as Yatsuhashi briefly trying to trick Coco until the announcer said Yatsuhashi was eliminated by Mercury.
Weiss and Winter talk alone where Winter saying she is leaving again soon because she was here to oversea shipment since the last one was attacked referencing volume 2. Also said that mecha they fought was just a prototype and the real thing might have gave them more trouble. Winter also reveals their family is unique since by bloodline they can use unique abilities like summoning which is the one thing Weiss is currently struggling with. Winter explains Weiss just needs to practice more as she casually summons a white grim type creature next to her as she pets it.
Ruby and Yang are with Qrow in their dorm playing video-games. They ask what his last mission was like where he gives short epic of an answer that pretty much annoys Yang. Ruby/Yang then pretty much brag how professional they are like what happened in end of volume 2, but Qrow dismisses that since they failed to stop the train to invade the area with grim. He also said stopping Roman didn't accomplish anything since someone else is controlling now which he remarks Ironwood won't understand. Yang asked how he knew the general and Qrow says he knows everyone to an extent like their parents as he shows them the picture of his old team which is giving Yang a noticeable reaction. Qrow then starts to leave, but leaves with a few words like don't get overly confident/don't thing after you graduate the hard part is over.
Winter then oversees Weiss practicing, but Weiss grows frustrated. Weiss says she can't do it where Winter slaps her and tells her if that is all her effort will amount then she won't win the tournament let alone be a huntress. Then smugly says if she wants to quit she can always leave Beacon and beg their father to be a receptionist or something. Weiss then angrly says she doesn't need him, but Winter says she needs his money though. Weiss then mentions how when she was gonna pay for lunch it was not working which Winter sarcastically says it was father cutting her off due to lack of contact. This pretty much pissed Wiess off and continues to practice which Winter says emotion can give her strength, but don't let it overwhelm her. Winter then gives Weiss to choices: Talk to her father again and beg him for his money back while explaining why she is in Beacon instead of Atlas or ignore him and forge her own path as a huntress. Weiss and Winter then separate after they embrace. As they walk away you can see a very small white sword from Weiss's latest practice attempt before it disappears which implies she is making progress. Later when Weiss's dad tries to call Weiss she ignores it which makes it obvious which path she took.
So alright episode. The fight was a predictable fodder stomp match, but episode wasn't just about the fight. Episode mainly centered around Weiss as she interacts with her sister. Reveals a few things like her bloodline perk and her tension with her dad. Shows that despite the military front Winter gives to Weiss she still very much cares for her. Qrow interaction with Ruby/Yang was casual as they played video games and it had some comedy especially during his "mission" tale, but it grows serious when he tells them to not get overconfident with yourselves. Also more about their parents which is more serious moment. There was a noticeable lack of Blake probably because unlike the other three she doesn't have a mentor figure to talk with which I won't be surprised she will get some screentime either next episode or soon considering the closest one to that is likely Adam
