The twin on Earth will be (much) older than the twin who boarded the
spacecraft. Assuming the twin on Earth and the twin aboard the spacecraft
to see each other via some instantaneous connection, the twin aboard the
spacecraft would see the twin on Earth doing everything at incredible speed.
The twin on Earth would see the twin aboard the spacecraft slow to glacial
speeds (as his or her velocity increased).
