1x20 Whistler's Mother (04)

Acting: Like a Man
Appearances: "Whistler's Mother", "Afternoon Delight"

Tobias reads Acting: Like a Man while in bed. Lindsay attempts to seduce him but he tells her "I'm trying to grow". ("Whistler's Mother") He is later seen reading it in bed again. ("Afternoon Delight")

The book appears to be an acting manual but it could possible be a guide for being more masculine in life.
