If you don't want to know the circumstances surrounding Friday's entry in this slideshow, then don't read any further...
[spoiler]Friday's quote:
Ep #224 (1967) - Jason - 'Well, you MUST tell me how you did it sometime.'
From "#0224/0225_0226: Robservations 10/29/01: Barnabas Makes Maggie's Acquaintance"
Barnabas assures McGuire,and he can deal effectively with Willie and keep him under control.
[/spoiler]
This Robservations is also in the period where there's little detail, and as such there's no reference to the quote. However, after Barnabas sends Willie off to "do that job that you have to do" and Willie instantly leaves to do so, Jason remarks that there been quite a change in Willie because he was never the kind to be an errand runner. But Barnabas counters that with, "Willie is
now an errand runner." This surprises Jason, to which Barnabas offers, "There are a lot of things about Willie that would surprise you." Jason asks how Barnabas managed it and Barnabas simply says he found a way. And after that is when Jason delivers the quote...
And this is the second quote from this ep. The first (Barnabas - 'You MUST be very proud of her') was back on September 14th.
