Misato and Shinji, with the back of Asuka's head in the foreground. Kensuke is absorbed in recording video. There is a strong wind.
MISATO:“Fine. And you, you've gotten taller, haven't you?”
ASUKA (BACK):“Yeah.”
dzzthink: Misato's remark about Asuka's height hints that they may have known each other at some earlier point. This may have been when Asuka was a major contender for being an Eva pilot and Misato oversaw some of her initial induction/training.
UrsusArctos: It's implicit in the first two episodes that Misato had just arrived in Tokyo-3 and the cold open of Episode 22' plainly states that Asuka had been living with Misato in Germany. So they don't just know each other, Asuka was Misato's ward for what's implied to be a significant period of time.
