Directed by Troy Adomitis, "Interactions" was written by Kevin Hopps, who researched all the available comic books he had that featured Electro.

After Gwen and Peter leave, an electrician, Max Dillon, attempts to upgrade the lab's electrical filters, but gets electrocuted and is sent to the hospital.

The battle leads the pair out from the lab into the rain, where Spider-Man spots a radio tower beside a pool: he knocks Electro into the water, causing him to short circuit into unconsciousness.

At school the next day Peter talks to Liz in the hall; she is complimenting his tutoring when the popular students approach, making her change her attitude, act rudely, and walk away.
