Building rapport

[FLASHBACK]

"Did you find it? The rope. Did you find it under the shelf in the wine cellar?" 

Not only surprised, but Bear felt a sudden chill down his spine. Bear kept a tight lip about what he found in the cellar, resorting to observing his boss's wife, as she was the most suspicious of all. Before the incident that night, Heaven had been going back and forth in the wine cellar.

At first, Bear thought she was just secretly chugging down wines. However, many factors somehow made it hard to believe.

Why would she need to lock the cellar securely?

Why was she being so discreet about it?

And why did she purposely leave it unlocked from the outside when she last visited the cellar?
