Ignis would rather run up the mountain for hours to get out of there- if the said mountain wasn't collapsing on them. That damn Empire ship was their only way out.

"There were four MTs on the ship- pilot, co-pilot and station guards- and Ardyn. If he truly tried to pull something, it wouldn't have been difficult overtaking the ship." Four MTs are nothing compared to the hordes of them they destroyed. Of course, that would lead to other complications like piloting the said ship, but he doesn't want to think about it. It ended the best possible way, even though the Regalia was away for a while.
