At a pool visit, it’s learned that Rize doesn’t know how to swim. Syaro suggests she practice using a kickboard, but there’s something Rize is more interested in trying.

リゼ:

“Being pulled along by the hands. I want to try that.”

あれ is used as the referenced concept isn’t something taking place involving the speaker (Rize) or the listener (Syaro).
