Giorno had just fought Melone's stand, Babyface, and was badly injured, to the point where he couldn't really do anything.

He was on the ground, scared. He thought that you and the others would think that he was in the turtle with Bruno and Trish and end up leaving him behind, and that he'd die.

He could only pray that one of you saw him.. he didnt care who, he just needed help.
