Back in the first or second arc or cable and deadpool, cable removed part of his brain and was basically powerless. He then got a special force feild that acted as a his new telekinesis and also got the power to talk to computers, sorta get his pyschic powers back. 
 
Now in messiah war he used his actual psychic powers against stryfe. Did he get his powers back or did the writer just now know about what cable did to himself?
