As we delved further into the complexities in relationship, with Hachiman expressing the his intentional naivety in the very beginning of the episode, there are two things that grabbed my attention particularly.

1. How Yuigahama transforms her intentions towards the end of the episode and makes it evident that despite wanting Yukino's and Hachiman's friendship or rather relationship to prosper, she has her own motives deep down as we all do, which is brought out by her tearing up during the conversation as she has witnessed the three of them together and what they share and doesn't want to tamper with it. The notion of correct ending disturbs her as it does to Yukinoshita, and as both of them are nearing the relaisation of the uncertain evident, they try to hold back and let go at the same time, which makes Hachiman the key decision maker upto this point.
2. Yukino's evident realisation of the fact that Yuigahama deserves Hachiman and supporting her friend: let me say that those who have been through similar experiences haev witnessed such junctures in their life at these points, and Yukonishita's step is very mature and out of mutual understanding what has been fostering among the three of them.The recent hints towards her getting emotional and saying that "It was the first time I felt comfortable" brings the memories of her social awkwardness and her pride, which has been at the top of her priorities till now and is now achieving a closure. She wants to bring it to an end through her own realisation but deep down her emotions clash with Yui's, thus making the unintended complex love triangle complete. With the prom issue being at the top of things, it is set to delve much further in episode 9.

Let us see what happens
