Hash data being altered when sent to class - ruby-on-rails

Question

My endpoint sends params to a class/worker.
def end_point
SomeClass.new.perform(params)
end
SomeClass starts defining variables.
def perform(params)
#variable = params[:variable]
end
If I do #variable.count in a pry session, it will return 2. But if I do params[:variable].count, it returns 1(the correct value). The data is being altered from within the method.
I tried renaming the arguments from params, I tried setting the variable in pry manually (this will result in 1), but when it is defined inside the method, it still results in 2. I inspected to make sure nothing is being altered sending from the controller. Any help would be greatly appreciated.
