Gosh, Kayness, that's his most intense scene there.
Each of these characters from The Room, are so well developed--not one vagueness in them! My own descriptions for these characters based on my trip of two midnight screenings :
Johnny: Works hard, loves unconditionally, wants a better world.
Lisa: manipulative, a cheater and a liar.
Denny: likes to watch Johnny and Lisa doing their thing. Loves Lisa, and eats an apple.
Chris-R: Pure gangsta.
People of truth:
Steven (appeared near the end of the movie, lol)
