YES, this is exactly what is wrong. Now, either this is deliberate and season six is gonna start with Lisa dumping his ass and Dean having a fresh hot meltdown and then ~stuff happens~ , or they expect us to take it on face value that the only part of the equation we need to notice is that this proves that Dean and Sam are OTP.

Like, guys, BE AN OTP. BUT KEEP LISA AND BEN OUT OF IT JFC.

Hey, my brand new scandalous idea is that Ben's dad is actually JOHN WINCHESTER. Yes I am a disgusting person. Now someone write me the fallout.
