No. 'Garbage In, Garbage Out' Wreck-Gar's first episode is about the nanobots that we first saw in Transform and Roll Out and Wreck-Gars story continues in 'Human Error II'. The entire premise of the Autobots helping out to restore their damaged reputations is the fallout from last season finales, 'Megatron Rising', Angry Archer first appeared in 'Home is where the Spark is'. 'Sound and Fury', Soundwaves first episode is an episode that is about Megatrons quest to get a new body, one of the main themes to season 1, ending when Megatron gets the key he first learns about in this episode to repair himself. It also ties into Soundwaves later episodes, 'Human Error I' and 'Human Error II', and introduces Prof. Princess who would reappear in 'SUV: Society of Ultimate Villainy'. 'Human Error I' builds on the entire season 2 arc of Porter C Powell having run Sumdac Industries to have gotten the Blueprints to make the Soundwave action figures that are a major plot point of this episode. It also builds on 'Sound and Fury' and most obviously leads into 'Human Error II'. 'Human Error II' besides most obviously building on 'Human Error I', and thus the entire run of Season 2's Powell subplot, it also ties in to 'Garbage In, Garbage Out' for Wreck-Gar, the altered Dinobot Island (and perhaps the break of Snarl from the other Dinobots) from 'Predacons Rising', and Scrapper being alone after the events of 'Threes a Crowd'. 'Nanosec', like 'Sound and Fury' is part of the season one major plot about Megatron trying to get a body. Nanosec himself returns in 'SUV: Society of Ultimate Villainy'. 'Home is where the Spark is, 'Blast from the Past', 'Nanosec', 'Sound and Fury', 'Nature Calls' are all main episode plots about Megatrons quest for a body, all but Nature Calls are spurred on my Megatrons persuit to build one, while Nature Calls is about finding his old one, leading into the two-part 'Megatron Rising' finale. A finale that also references every episode from that season except 'Headmaster' and 'Thrill of the Hunt', which will both be used both for multiple later episodes. Emphasis there on smalll ways. Outside of the relic hunt, there really hasn't been an overall plot arc that Prime has gone on. It's meandered around all this time. Again, Animated had a very clear flow for each season. Season 1. Megatron getting his body. Season 2. Megatron building a Spacebridge and enacting his plan to conquer a helpless Cybertron. Season 3. Megatron gaining control and then exploiting Omega Supreme to conquer Cybertron. Even BW did this to a degree: Season 1: was a bit all over the place, I'll give you that, but it did introduce all the elements that would be utilized later and had a buildup of the Vok and their realization that the BW is going on. Season 2: Buildup to the Ark. Season 3: Protect the Ark. Heck, even the season finale for Rescue Bots references at least 8 episodes. Prime did nothing but waste time leading into Unicron that came from no where and resolved just as quickly for it's first season finale. Read what I wrote. Superlink. And yes, Superlink is far better than Prime. Because none of the other shows set up for it to happen and then didn't go through with it. They set up and were going to kill Raf until a last minute change of their minds. The writers have outright stated that. Hence the part of the prophecy about "The weak perish", it was supposed to foreshadow Rafs death. Bulkhead got everything a character gets when they die midseries. He got a montage, he got the motivating speech, his uncertain fate was teased more than once as a cliffhanger ending. Structurally, he should have died. Instead he's just limping on as a completely unlikable character for no discernable reason. That's the difference. It would be like 'Code of Hero' not killing Dinobot at the end and instead he showed up a few episodes later just fine. Speaking of which, Dinobot and Rhinox not being main characters makes me want to ask you what constitutes a main character, since both died well before the ends of their series.
