I've been thinking about how the Scimitar and Vengeance were able to catch the Enterprise in their respective movies. Both the Kelvin Ent and the Ent-E were punching it at maximum warp. Both were caught by the enemy ships and fired at, causing them to drop out of warp. Neither the Kelvin era Federation nor Remans had transwarp drive. How do you figure the bad guys were able to catch up to the heroes?
