What has the last year been like for Sergio?

The last year Sergio has spent a lot of time at the firehouse. Gideon even came to visit them in Red Hook. Sergio's mother made dinner, and they watched Jeopardy! afterward. Gideon helped Sergio with his homework, even though Sergio did not need help. Gideon taught Sergio basic first aid, and they studied together when Sergio had a test in biology.
