Major Story Arcs
Trusted to manage Kingpin's affairs, he is extremely loyal and skilled in his work managing Kingpin's criminal enterprises and affairs. Kingpin orders him to locate Nuke, and although he initially objects because of the "domestic" nature of the job, he follows through on his orders despite the difficulty he has in pulling all the required strings. When Kingpin stages Nuke's assault on Hell's Kitchen, leading to the loss of perhaps hundreds of lives, Wesley protests. This is less because of any moral qualms than a fear as to what the results of such an action may be if they are connected to it by the authorities. After the plan fails, he alerts Kingpin that Nuke has escaped his captivity. His ultimate fate is unknown.
