Where is Jack?
He must watch TV.
Here, I think he wants to make deduction using must.
Is it correct to use must this way?

 

[GoesStation]

No. You can say He must be watching TV.

Right. "He must watch TV" has completely different meanings. It can mean:

- He is being forced to watch TV. (Someone says he must.)

- He is addicted to watching TV. (He must watch it or go mad.)

It's possible when talking about regular/repeated actions: He knows all about every series that's on at the moment. He must watch TV every day.

That, too! Good point.
