Nope. What he did was look to see if he was going to die. Earlier he said that he was going to die 17 years before he got into MacLaren’s body. 17 years before was 2001, the year of 9/11. Therefore he was supposed to die because he was in one of the twin towers that got destroyed, but instead the plane did not strike the tower. He lives.
Agreed with respect to the timing. Grant Version 2 was in the North Tower, which was struck at 8:46 a.m. and which collapsed at 10:28 a.m. He would have had about 14 minutes to leave the building before it was first hit -- if he had wished to do so. He might have planned to die. Maybe we will find out, if there is a Season 4.
I think he just decided to try to escape before the plane(s) hit ... he did kill MacLaren 17 years before he was supposed to die though. Why not live out your life instead of sitting there in the tower ... he already helped by alerting ??? to the asteroid. Hopefully they can develop an X-Ray laser or whatever and deflect it, they have an extra 17 years to do so.
