On this episode, Kirito figures out about Death Gun's scheme. Later, he comes up with a plan with Sinon.
So even though there's no action whatsoever, Kirito saying his thoughts to Sinon was alright just like in the novel. Also it's nice to see more details of Death Gun and how he's killing people. Anyway, I'll be looking forward for their next battle against Death Gun. Overall, cool filler of the next battle.
Conclusion: Cool filler for the next battle.
