[spoiler]Tuesday's quote:
Ep #336 (1967) - Dr. Woodard - 'It MUST have been a very extraordinary reason that brought her back after all these years. I think once we've uncovered that reason, Julia, we'll... we'll finally have arrived at the truth in this twisted situation.'
From "#0335/0336: Robservations 01/30/02: Woodard on the Scent"
When Vicki tells her Woodard is in the study looking at Collins family books, Julia becomes concerned and hastens to the study. Woodard is there, poring excitedly over the many volumes. The original Barnabas had a sister named Sarah, he points out, and he, Dave, met Sarah himself at the mausoleum! Ridiculous, she says, looking very fearful at this turn of events, and she suggests he's tired and overwrought. Dr. Fisher thinks David is hallucinating. Woodard reminds her Sam saw Sarah, too, and Julia retorts Sam probably saw Sarah instead of pink elephants, being the drunkard he is. Well, he knows he saw Sarah and he intents to find out why she came back and get to the truth of this situation--he won't rest until he knows.Julia's lip curls with dismay.

Well, in this Robservations the quote is merely paraphrased with detail left out.
What actually happens in the section leading up to the quote and afterward is that after Julia makes her rather condescending remarks about Sam's reliability (though we know she would say anything and impugn anyone to protect Barnabas), Dr. Woodard says that he doesn't care if Julia discredits every bit of evidence he mentions. To that Julia claims she's not trying to discredit him and attempts to appear sympathetic by saying she's worried about him - he needs rest. Though while Dr. Woodard appreciates her concern, it's not necessary - he insists he's not tired, upset or conjuring up ghosts. Dr. Woodard then insists that he saw Sarah as clearly as he sees Julia. He talked to Sarah and she talked to him. Now that he knows she exists, he's going to find out why. Julia questions that and it's then that Dr. Woodard delivers the quote. Julia then remarks that Dr. Woodard appears to really believe that, and after he confirms he does, she asks what he's going to do about it. He doesn't know exactly - but he does know he's not going to rest until he finds out why Sarah Collins has come back to earth. Julia is far from happy to hear that and her lips curl in dismay.
I love how Dr. Woodard refers to the situation as "twisted."
