Here’s where the whole “Oops Rachel Was A Secret Plant” bombshell hits the wall.  Like, honestly, it’s just a random cruel thing to do.  It’s only poignant in that Joe… isn’t going to “hulk out” as he laments here.  He’s just going to be devastated.  That’s not fun.  This was a dumb idea.  Way to go, David!   Don’t try to build up pathos just because you feel expected to!  Fix this later!
