"Lexi, Watch your language." Said Della.
"Cut it out, Della. I don't care about you and your investigation anymore." Said Lexi.
When Lexi proceeds to pull the trigger again, Robin rushed to stop.
Meanwhile, Della carried the old lady. Della and Arthur along with the old lady ran away. Lexi faints after fighting with Robin. Robin follows Della and Arthur. After a while, Isabelle became conscious.
"What is the relationship between you and Lexi?!" Yelled Della.
"I can't tell you..." Said Isabelle.
"Did you hide the treasure?" Asked Robin.
"No." Said Isabelle.
"What is your motive?" Asked Della.
"Can you stop asking me questions like as if I am your ally?" Asked Isabelle.
Della felt hopeless and elucidated Isabelle about their current situation.
"Do you realise how many people have suffered because of this?" Asked Della.
Isabelle remained silent.
"They are my grandchildren." Said Isabelle.
"What do you mean by them?" Asked Della.
"One of them is Lexi, you find who the other one is." Said Isabelle.
"Crap, does this mean Lexi is a traitor?" Asked Robin.
"Isn't it obvious?" Said Della with tears in her eyes.
"Where is the treasure?" Asked Della.
Isabelle elucidated the location of the treasure. The treasure was hidden in an island called Capri.
Della and Robin travelled to Capri in a speedboat. They were many tourists roaming.
"Do you think Lexi will be here?" Asked Robin.
"I guess. We don't know who Lexi's sibling is, so we should be careful until we know their strength and ability." Said Della.
They headed to the place where the mask was hidden.
Isabelle told them the exact location of the mask.
When they got there, the sky was suffocating gray.
It was an abandoned building with a broken roof.
Della and Robin went in separate ways.
Della was standing in the middle of the abandoned building.
The air whistled behind her hair, she instantly turned around.
She wanted to go inside the building and explore... once again.
