== Synopsis ==
: Few who live in the great house at Collinwood will ever learn of the evils that take place this night, for in the Old House on the Collins estate, a bizarre form of revenge is about to occur. 
Sam teaches Adam to speak more words. As Barnabas suffers from being chained up in the wall, Adam also feels pain. Trask holds a trial and calls all of Barnabas's dead victims from 1795 and 1796 as witnesses. Barnabas is then sealed up in the wall after the verdict.

== Background information and notes ==
=== Production ===
* Jane Draper returns for a final appearance as the character of Suki Forbes, who was last seen in 424. The role of Maude Browning was previously played by Vala Clifton in 441, and Ruby Tate was previously played by Elaine Hyman in 414.
* There are no cast and crew credits for this episode.
* The copyright date for this 1968 episode is given as 1967.
=== Story ===
* GHOSTWATCH: Reverend Trask's ghost appears to Barnabas and summons the ghosts of Jeremiah Collins, Ruby Tate, Maude Browning, Suki Forbes, Nathan Forbes and Ezra Simpson. 
* INTERNAL MONOLOGUE: Julia: Where's Barnabas?
* TIMELINE: Sam mentions it was yesterday when he figured out that Adam was the one who kidnapped Carolyn.
** The date of Nathan's death is given as March 31, 1796, which occurred in 460. This is the first time a year of 1796 is stated in relation to the events of the 1795 storyline, although a year change was implied in 413. A date of March 31st would be in line with 463 taking place on April 3rd, which from Victoria's point of view took place soon after.
== Bloopers and continuity errors ==
* Joe refers to Carolyn Stoddard as "Carolyn Collins" while talking to Sam after Adam has left.
* There are several paintings displayed under the windows in the Evans cottage that weren't there before. Also, the sailboat painting he was working on before aging the portrait of Angelique is back on the easel. Maggie has been gone and Sam is blind, so who would have put them out? (Maybe Adam?)
* David Ford flubs a line in Act II: "After he was awhile here..."
* It is stated to have been a "few days" ago when Adam first stopped by at the Evans cottage (occurred in 508). However the on-screen passage of time would suggest it was yesterday.
* In Act III, when Reverend Trask is telling Barnabas that he will convene a trial for him among his dead victims, Jonathan Frid seems to forget his lines and says nothing for several seconds except what sounds like a quiet "No." He looks off-stage, and then Jerry Lacy, waiting for Frid to say his line, also looks off-stage before proceeding with his line, "And now, Mr. Collins..."
