Marvel: Liberty & Justice for All

As part of their training at the New Charles Xavier Institute, Triage and Tempus are allowed to attempt their first solo flying mission. Some way into their mission, they pick up an urgent SOS message – Sentinels are attacking a superpowered mutant, who is struggling to protect an injured politician. When they abandon their lesson and answer the call, however, the identity of both will cause the two young X-Men far more problems than they bargained for.
