Research direction

Read _episodes/10-aggregations.md and _episodes/11-joins.md to decide where method chaining fits best in the lesson flow. Add an introduction and example showing its logical flow and reduced intermediate variables; done means the concept is present in the selected episode and remains consistent with the surrounding lesson.

Written by the indexing model from the issue text.

Description

I think method chaining should be introduced, either after the aggregation or join episodes. It's a very effective practice to organise pandas code, leads to very clear logical flow, and fewer intermediate variables.
