After Luke attends his retirement party, Barry (Milan Carter) informs him that he needs to go on one last mission to extract an operative (codename Panda), as her comms have suddenly been cut off while on a mission in Guyana. The mission revolves around arms dealer Omar Polonia’s son Boro, who wishes to continue his father’s legacy and widen his illegal arms distribution circle. Luke reveals that he was the one to push Polonia off a cliff to his death, and to ensure that his son doesn’t turn out like his father, he put Boro in the best schools and even paid for his higher education. Turns out, his best intentions did not help Boro transition into a better man than his father — if anything, Polonia’s murder drove him to further uphold his criminal legacy.
Boro’s case files also indicate Luke was undercover as mercenary Finn Hoss when Polonia was alive, and it is likely that he was able to forge a close friendship with the arms dealer before killing himself as a part of Operation Junglebook. This explains the smiling photographs of a young Boro with his dear uncle Hoss, giving the former little reason to doubt Luke’s cover when he re-emerges when he’s about to sell his suitcase nuke in an auction. For Boro, Luke is the cool mercenary uncle who was like family to his father, and someone who continued to take care of him financially as he grew up. Boro openly acknowledges this, thanking Hoss for sending care packages and funding his education, which helped him become the man he is now.
But Boro, of course, is unaware of Hoss’ true identity and welcomes him to his paramilitary compound with open arms. That is, until, Luke’s cover is blown to smithereens.
