The father runs out side to the back of the house and sees the water still splashing out of the above ground pool. His son, the grand son stands in the chest deep water "dad this is insane, it was loud a second ago and now the waters shaking!" As the grand father walks out from the back door "roger what's all the panic for?" The son does not look back and shouts "Oscar I need you out of that pool right now." The grand son looks up and is saddened "but dad this is getting so cool!" The dad refusing to take a step further "buddy, i need you to do this NOW!" Roger looks back at his father "you said he left!" The father shrugs down ward "I said he was gone" as the grand son walks up to the two dripping wet "who's gone?" The father stiffly replies to his father "left and gone mean not here anymore, they mean you won't one day watch him rise from under a pool where my son, your grandson is playing, it means for 30 years there is not gonna be a secret in the back yard!" The grand father looks at the grandson "oscar, I had a friend from far away come stay with me a while, the weird thing is your dad thought he left but he just needed to.......... i dont even know how to say it 'sleep'. The grand son looks back at the pool "theres a secret lair under the pool! When do we go down there! Dad why didn't you tell me grandpa has a hero base under his house!" The father pulls the son close as he tries to walk to the pool "theres no hero here, not to me anyway"
