[spoiler]Sunday's quote:
Ep #43 (1966) - Maggie - 'Well, then it MUST be either Roger Collins or Burke Devlin.'
From "#0043/0044: Robservations 06/18/01: Coffee and Conversation"
This information you think Pop has, says Maggie--it concerns somebody else, right? Yes, says Malloy, sipping his coffee. Then it must be either Roger Collins or Burke Devlin, says Maggie. Why did you say that? asks Bill--did your father mention either one of them, or both? Not exactly, says Maggie, but they've both been to the house, and no one else has--it stands to reason it has something to do with Burke coming back to Collinsport. Then you have noticed something different about your father since Burke came back, says Bill. Sure, says Maggie

The Robservations references the quote perfectly...
And this is the second quote from this ep. The first (Bill - 'Only I MUST say Sam makes no secret of it') was back on August 15th.
