OK, then, here's my advice. Right after he breathes in the shirts, hoping for the scent, his face up close to the cloth -- watch for the left 1/4 inch or so of his mouth to twitch three times, as if he's saying three one-syllable words. Listen for him to make three short sounds, ditto. It won't sound or look particularly like "I love you." He could be saying just about anything, or twitching for some other reason. But that's the reason that makes the most sense -- and is the most emotionally thrilling -- to me.
Then, immediately -- and I mean IMMEDIATELY -- afterward, it cuts to Mrs. Twist in the kitchen. So if you get there and haven't seen it, rewind slightly and try again.
Good luck! Report back tomorrow!
