Re: Understanding the theory of special relativity

So according to Hachel:
 When Stella is back, Terrence and Stella are co-located and
stationary to each other, and both can see both clocks which are
side by side.
 Terrence can see that his watch shows 13.5 years.
and Stella's watch shows  nine years.

Stella can see that her watch shows 9 years.
and Terrence's clock shows 13.5 years.
