Act 21: What Did You Do to Ami! (亜美ちゃんになにをした!　/ Amichan ni Nani wo Shita!)

4:06 Shiokara

Shiokara is pieces of seafood such as squid or tuna in a brown paste of the salted and fermented 
entrails. 

6:22 Two girls playing

They're playing "atchi muite hoi", this game is usually coupled with 
"jan-ken-pon" (Japanese equivalent of Paper, Scissors Rock). In this variant.
Jan-ken-pon is played, the winner says "atchi muite hoi" immediately after
and points in a direction and the loser tilts their head to look in that direction.
The purpose is to confuse the loser into looking the wrong way.

6:59 Nameplate reads:

Mizuno

7:14 Pardon my intrusion

"Ojamashimasu" is a greeting used when entering someone's home.

8:14 Makoto's meal

This is "okayu", a kind of rice porridge. Since its easy to digest, it's the go-to
meal when people are ill. It seems Makoto has put some apples, kiwifruit
and umeboshi (pickled plums) and chopped spring onion as an option on the side.

19:30 Makoto and Trees

Though not expressibly stated. The planet Jupiter is tied to the Chinese element of Wood
through its Japanese name "Mokusei" (literally, Wood Star) and the name "Kino" cotains the
same wood character, underlying Makoto's connection to it. It also appears in certain attacks
such as Flower Hurricane. Hence, Makoto's ability to listen to the trees in the same way Ami
has been seen listening to water in other episodes.

23:47 There's no point in running

A dark callback to the earlier episodes of the series when Sailor Mercury would 
sometimes say this same line.
