Pippin:
How do we know that the current Filch is the same person? Maybe Tobias
took the place of the real Filch, who is off some where enjoying a quiet
retirement. Snape had to get his acting talent from somewhere -- maybe
it comes from his dad, who has been taking polyjuice all these years.

We can suppose that Fake!Filch was only pretending to side with Umbridge.
After all, we don't hear that he actually flogged anybody, do we? I still
think it's very strange that in PS/SS Snape goes to Filch to have his leg
bound up and speaks to him very familiarly -- like an equal.
