So that people will still be able to tell what's being talked about, here's the shot/caption from Ep #314:
1967: Ep #314 - Dr. Hoffman encourages Willie to keep what
he's learned a secret from Barnabas for David's sake. And here's the shot/caption from Ep #315:
1967: Ep #315 - Dr. Hoffman tries to persuade Barnabas not
to harm David if he finds him. (The expressions on their faces do indeed perfectly encapsulate their '67 relationship.)
And while we're at it, I have to add that I love this moment from 9/8's Ep #54
1966: Ep #54 - Burke accuses Roger and Sam of having set
him up. (Love the expression on Roger's face.)
And this moment from 9/8's Ep #836
1969: Ep #836 - 1969: After Julia declares that David is dead,
Quentin's laughter fills the room.
