We need to determine what Hugo believes about the location of the dusty tablet based on his observations/actions.

Given timeline:

- At 8:00, Hugo carried the dusty tablet to the east wing.
So at that moment, Hugo knows he moved it to east wing; thus after 8:00, he believes it's in east wing.

- At 8:01, Uma took the dusty tablet and placed it in the rooftop terrace.
Hugo may not be aware of this action unless he observed it. The description says "Uma took the dusty tablet and placed it in the rooftop terrace." It doesn't say Hugo saw it. So we assume Hugo didn't see that; he might still think it's where he left it (east wing) unless later info changes his belief.

- At 8:02, she carried the old wrench to the mail room. Not relevant.

- At 8:03, Hana brought the old wrench over to the cafeteria. Not relevant.

- At 8:04, Hugo reorganized some papers on the desk. He is doing something else but maybe sees the tablet? No mention.

- At 8:05, he refilled a cup of coffee.

- At 8:06, he checked their email.

Thus throughout after 8:00 until end, there is no indication Hugo learned that Uma moved the tablet. Therefore his belief remains that the dusty tablet is in the east wing.

Answer: east wing.
