When paramedic gives electric shock to Vidar, electricity rather flows back from Vidar's body to the paramedic, making the paramedic fly some 5 feet through air. Well, Vidar is shirtless and his body is in direct contact with the earth, plus there is rains and his body is totally drenched and there is water on the ground, that further increases electrical conduction, therefore, simple physics rules state that electricity from Vidar's "earthed" body would have all gone to earth and paramedic was not supposed to get a shock from reverse electricity flow, whatever the mythical powers of gods and giants might be.
