It was a great filler ep.
Things I took from this ep:
-Megatron thinks very little of Starscream. But it could have been the way he barged in, and started talking without making sure he had Megatron's full attention.
-I thought Silas was dead, the months of torture was an interesting way of having him one last time.
-Knockout's feelings toward experimenting with Brakedown's corpse
-Silas' line about Starscream's T-Cog and feeding it to Knockout was great
-Starscream's idea to use dark energon was great. But they obviously fell into the same flaw as Ratchet's error. The untested Synth-N should be tested on smaller non-sentient machines
-this definetly answers that question what happens when you mix dark Energon and Synth-N
-the range of emotions from Starscream and Knockout were great....both fear and comedic value.
-even them running was fun to watch, Decepticon warriors indeed
-that bit when Starscream threw Knockout under the bus was well played
-I found it facinating Knockout spent the time to watch human movies, I wonder how many he watched? and what other kind of movies he's watched?
-great to see Airachnid fighting again, and getting splattered against the wall
-I believe Soundwave transported Airachnid and co to an asteroid rather than a moon....based on the display on his visor.
-homages to G1's "Dweller in the Depths" and Blade II
-outright stating Beast Machines was a nice touch
-interesting way to have Shockwave in the episode without being heard or even seen...as I read somewhere...bluetooth.
-didn't notice Airachnid's "bite" till my 3rd viewing
-Soundwave taking care of business again!!!
-if this had been a longer season, this could have been a great 2-parter
-Since Airachnid is not dead, how will her future appearances work? Unless it's been stated this was her last episode...
-awkward pause between Starscream and Knockout was funny
Even though it did not further the Beast Hunter's portion of the arc, this does help the Autobot's cause as half of the troops Megatron had is no longer available.
Here's a thought: if somehow Airachnid and co manages to make it to Cybertron, could they feed on the corpses? Sure, dead Autobots and Decepticons no longer have sparks, but are their dead like us? Once dead, our blood stops pumping and dries up. If you decaptitate a Cybertronian, sure some Energon is lost, but would there be enough remaining in their systems for the zombie Insecticons to feed and revive?
