He later witnessed the deaths of Seal Team 10's Bravo Unit at the hands of Fortune.Raiden later met Peter Stillman, although their meeting occurred awkwardly when Raiden mistook the latter for a bomber at work and held him up, and was tasked alongside Pliskin to freeze the detonators of C4 to ensure they at least weren't an immediate threat.Raiden eventually learned of the Patriots' existence, as well as the development of Arsenal Gear, an enormous warship for which the Big Shell acted as a disguise.He also rescued Arsenal's AI engineer Emma Emmerich and attempted to escort her to safety, although she was later killed by Vamp despite his best efforts.Now living a life in the United States, Jack joined the military where his admirable skills were at first recognized by the U. After they parted ways, they met again afterwards, shocked that they worked in the same place.Eventually, Jack grew to love Rose deeply, but his harsh experiences had left him melancholic and emotionally distant, and he constantly shut her out of his problems.
His skills with a bladed weapon, as well as his cruelty in dispatching enemies with them, was another reason for his "Ripper" nickname.
Jack and other surviving members of the Small Boy Unit then underwent extensive amounts of counseling before becoming at least outwardly stable.
There, Jack came into the hands of the Patriots, who implanted his cerebral cortex with a high concentration of nanomachines, in order to have him function as a back-up system for an optic-neuro AI.
He later revealed this to the Colonel, who was surprised, since there wasn't supposed to be anyone other than Raiden who should have infiltrated the base.
His suspicions that there was another intruder were quickly confirmed, as he entered a room full of knocked out guards and caught a glimpse of the man as he ascended in an elevator.
