Hey Ben,
Do you know I actually had those episodes written down in my 2001 daytimer? I was excited because Sci-Fi had just started airing Dark Shadows from the very beginning, and I was able to see the pre-Barnabas eps, which I had never seen before.
According to my records, episodes 11 and 12 aired on May 24th, and episodes 13 and 14 aired on May 25th.
Hope this helps you and your friend.
Regards,
Cassandra Blair
