I am puzzled by the time dilation in special relativity.

The clock somehow slows down in a moving frame of reference according to the Lorentz transformation. That seems to come about because some frame is considered 'inertial' as some other frame is 'moving' relative to it. The CLOCK in the 'moving' frame is then slowed down. However, the moving frame is actually the INERTIAL frame to the CLOCK or the TWIN residing there, while the 'inertial' frame is actually the MOVING frame speeding away from it. The clock in that 'inertial' frame would then slow down instead.

If the space travelling teenage TWIN come back to earth after a grand tour around the milky way & meet his brother on earth, he may find his twin brother a centenarian (or six feet underground). The travelling CLOCK may have slowed down by 90 years relative to the earth clock.

What would happen if his centenarian twin on earth come meet him in the space ship instead ? Would the earth clock have slowed down by 90 years relative to the travelling CLOCK ?

Yes gravitation effects had been ignored in this Gedanken scenario.
