Final answer:
The killers' individual escape plans differ in their approach and methods.
Step-by-step explanation:
The killers' individual escape plans differ in several ways. One major difference is the approach they take to their escape. For example, one killer may plan to break out of prison while the other may plan to create a diversion and escape during the chaos. Another difference could be the tools or methods they use to carry out their escape. One killer might use a disguise or fake identity while the other might use brute force to overpower guards.
