Zeke Jaeger was about to use his 'scream' to turn the person who had drunk his spine into a Titan, Falco Grice was no exception. His act were interrupted by Colt's plea who was standing in front of Falco. However, his efforts didn't make Zeke stop his act, explosions from the Titans' transformation appeared through his screams. Zeke really did it. You ran to grab Colt's arm, try to prevent him, including you, from accidents. The scene was terrible.
