Convert a multi-level array to a normal array

I have a query that creates the following result:

ArrayOne: Array
ArrayTwo: Array
  -> 0: Object
     -> res: Array
         -> 0: Object
         -> 1: Object
         -> etc

How do i bring “res” to the root of the results so it will be like this:

ArrayOne: Array
res: Array

Thanks a lot
