Head Case

T1, E3: When Grace (Debra Messing) moves in with Will (Eric McCormack), she complains that the guest bathroom is too small and suggests knocking the common wall down to create one big master bathroom, which results in Will having to confront his own issues on change and his ability to have a successful relationship. Meanwhile, Jack (Sean Hayes) and Karen (Megan Mullally) bear the brunt of Will and Grace's displaced anger.
