If you don't want to know the circumstances surrounding Monday's entry in this slideshow, then don't read any further...
[spoiler]Monday's quote:
Ep #910 (1969) - Julia - 'She MUST either know or suspect that he is really Quentin Collins.'
From "Robservations 4/25/03 - 909-910 - Grant Goes With Olivia; Music For Q's Memory?"
when I went to the hospital to get Grant, he said he didn't want me to treat him anymore, refused to come with me. Why, asks Chris, if he has amnesia, would he turn you down? He left with Olivia, reveals Julia. i don't get it, says Chris--why is she so interested in him? She either knows or suspects he's really Quentin, says Julia--let me see the x-ray. She holds it up to the lamp and says, now I know why she's so interested in the painting--there's another painting under it--a portrait!
The Robservations doesn't reference the quote exactly, but it does reference it well - though it shamefully leaves out the word "must"...
