No problem

[Luckily, Shaddow was nearby and saw what was happening]

Jay forgot to press the "Transform into fast submarine" button.

Shaddow dashed into the lost city while transforming and saw Jay's car....

"Jay, Jay, do you copy? It's me Shaddow." Shaddow said via video call.

He put on his "suit" that let him breathe under water and dashed out..
As he reached the car, he saw Jay unconscious in the car.

He rescued Jay by dressing him in the "suit". He carried Jay to the sub.

Jay woke up several hours later......

Just then, a call came in..

"We've got the exact location of Lt J&M.. They're 30km north of you.. Good Luck"
