>After the destruction of Requiem all hope for him to reunite or even catch a glimmer of what was left of his love was impossible
Edit.
The didact gifts chief the Cortana subdivision which completes weapon's AI capabilities while also making her look more like CE Cortana's changing her color to her original purple.
It is implied Medicant Bias is still in the systems watching, delaying the efforts of the intruders allowing Chief to out maneuver them.
A proto-gravemind forms in the Ark once more and takes out What's-her-face with him before the finale where everything blows up to hell. The didact reunites with Medicant Bias having an exchange in text a la Marathon understanding that both share the same flaw, having both justified their madness with a pretext that it was for the greater good having forgotten what they were actually protecting.
The didact leaves the galactic system with Bias, and shuts down the Ark decommissioning the Halo array with it, as the Flood seems to have perished for good.
Master Chief has multiple conversations with Atriox in the finale, Atriox giving him the old "We are not so different you and I" speech. Atriox attempts to have a final mano a mano with John but to his embarrassment he is not only humiliated, he attempts to flee only to be fired upon by an elite and grunt squad dying an ignoble death instead of the glory he wanted to embrace..
Master Chief and Blue Team live long enough to retire, John reuniting with Kelly.
After fighting Atriox, confronting Cortana, talking to the Didact and engaging Gravemind a final time John comes to terms with his eventual retirement realizing that what all of them had in common is that all of them thought they were justified because their actions were backed by their beliefs in a greater good.
