Well, this was unexpected!
Having Botan narrate everything form a boar’s perspective is original. Appart from that not much can be said from this episode. It was pretty standard. A little story was explained and we got to see a bit more from the characters when they aren’t in front of Tomoya.
I found it pretty weird that Botan would drown just because Kyou told him not to move. I mean, I get that Kyou is her “master” and that he loves her, but I thought animals had a stroger common sense than humans…
Also, Botan understood fast that Kyou was in love with Tomoya, and this makes me think that he is a reincarnation of Akiko from Kanon, since both characters seem to be omniscient about everything around them.
