 - [ ] 4. Create a relationship between Episode type and Character type in your schema. Please have a look at the [documentation of the episode endpoint](https://rickandmortyapi.com/documentation/#episode-schema) to see how to get the episodes of a given character (heads up! we are calling the field in our Characters `episodes` but the REST API is calling the field that returns an array of episodes as `episode` - singular!). Hints:
 
   - You need to add a `Character` key in the resolvers object and an object with an `episodes` key in `Character`. Similar to the Author type and books field in the [Apollo documentation](https://www.apollographql.com/docs/apollo-server/essentials/data#resolver-map). Hint: The first argument of the resolver is the 'parent' type, in this case, the parent of the `episodes` field is the `Character`. parent.episode gives you the array of episodes returned from the REST API.
-  - You can filter the episodes in our case using the `mapEpisodeUrlToEpisode` defined at the bottom of this file `src/index.js`.
+  - You can use the helper fetch functions defined at the bottom of this file `src/index.js`.
 
 - [ ] 5. Create a query that returns a single Character given an id. You need to fetch the character using `https://rickandmortyapi.com/documentation/#get-a-single-character`. Hint, you need to use [arguments](https://graphql.org/graphql-js/passing-arguments/)
