There were no Gigi scenes in episode 3.
So, I am gonna continue with episode 4 (:
Constance comes back home (Sylvia's house) and sees someone doing something with the lock. She thinks it is a thief but it is actually someone Sylvia called to fix the lock.
Patrick and Jessica are encountering financial problems, and kind of 'tricked' Ching Yeung into giving them money. Constance is asked to keep this secret.
