Just finished watching
this episode - Wilfred in full flight is something to watch. Being "possessed" by Sneakers, Wilfred is even more ingratiating than usual and yet he uses this to work so hard on Ryan and Kristen's "issue" that it just becomes hilarious.
I think Wilfred's approach is summed up by this quote: "Anger is like herpes: You're not meant to keep it to yourself".
