SOQL - Query Session date from Junction Object

I have the following:
User-added image

Attempting the following query:
SELECT Id,(SELECT Session_Date__c FROM Session__r) FROM Session_Speaker__c

Returns:
Id,(Select Session_Date__c FROM Session__r) FROM Session_Speaker__c
                                                    ^
ERROR at Row:1:Column:40
Didn't understand relationship 'Session__r' in FROM part of query call. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name. Please reference your WSDL or the describe call for the appropriate names.

I'm not sure what I'm doing wrong. I'm very clearly inserting the __r as the error message suggests. The Session Speaker object clearly has the relationship I'm attempting to utilize. The session object clearly has the date field I'm attempting to query.
