Agent C realized that something was off in MIB’s UK branch since High T and Agent H defeated the Hive. He secretly launched an investigation and strongly suspected that agent H was involved due to his erratic behavior. This led to C constantly clashing with H over the dereliction of his duties. Agent C helped uncover High T as the mole and assisted Agent H with his plan to settle the matter quietly. He later expressed his support for Agent H to be appointed at the probationary head of MIB’s UK branch.
