In The Making of The Room: Old Sins, the following unused letter can be seen in the early development stages of the game.
This letter happens to be the same letter seen in the first level of The Room Two - the letter left in the crypt by one Mr. Rigby, with instructions from his mysterious employer. (There are a few changes, but the gist of the letter is unmistakably the same.)
So what does this mean? For me, this letter both inspired and confirmed the theory that Hugo Waldegrave was the wealthy benefactor that paid Rigby to collect the Null artifact in the crypt.
First, let’s look at this unused letter. We see a preliminary version of the Waldegrave crest, with the buck and the swan, and the motto “Scientia ipsa potentia est”. The stationary reads “The House of Blackmoor”, and the letter is signed by a “Mr. Gillingham”. We know that house motto and these names were eventually scrapped, but there is evidence that the developers already had the name Gillingham in mind as far back as The Room Two, with the original drafts of the Rigby letter. Here’s another image from The Making of The Room Two:
Despite the poor quality, at the bottom a signature can be seen: “S. Gillingham”. So evidently, the developers had plans to make the enigmatic Mr. Gillingham a character in The Room: Old Sins, but changed his name during development.
Thinking about this, a lot of things started to make sense to me. For years, I had only played the mobile versions of the games, and after playing the remastered versions for PC, I noticed that the indecipherable signature on the Rigby letter, which had always been there in the mobile version, was gone in the remastered version. Here’s the original version for context:
I couldn’t understand why they would remove this signature. But after considering that Hugo Waldegrave might well be the author of the letter, it helped to piece together the potential reasoning. The developers were working on the remastered versions of TR, TR2, and TR3 at the same time that they were developing TROS. Is it not possible that they might have been working on a new version of the letter (the first image) to include in TR2 for PC? After all, where would this letter have appeared in TROS, and why? But, as we can see by the unused names, address, motto, etc, the developers were still coming up with an identity for the Waldegraves. So the next most logical solution would be to simply remove the signature from the letter, leaving the possibility that it was written by the patriarch from TROS open without requiring the developers to have a name set in stone yet.
Outside of the evidence of developer intentions, Rigby being hired by Hugo Waldegrave checks out within the canon of the games. Waldegrave was an inventor and explorer known for his fascination with exotic artifacts. It would be entirely in-character for him to hear of an ancient and powerful artifact and want it for himself. The massive amounts of debt he took on during his lifetime also speak to his willingness to throw money away on legends, such as those pertaining to the Null. The writer of the letter is also evidently a person of status, like Waldegrave. Everything would fit within the timeline as well - the letter to Rigby (in every version) was written in 1883, and we know Waldegrave died in 1908 at the very latest.
There is also the matter of their mutual acquaintance, Professor de Montfaucon. In The Lab of The Room Two, Montfaucon has a framed collection of exotic beetles in a cabinet. These beetles are labeled in a font which is noticeably different from Montfaucon’s own handwriting, which is seen in two other places in the level. In The Room: Old Sins, Hugo Waldegrave has a very similar collection of beetles in his curiosity room, and the gems in one of his display cases are labeled in the same hand as the beetles in the lab. Now, admittedly, the labels in the display case are actually directly repurposed from The Room Two (with the fun side-effect that the gems are labeled with the scientific names of beetles). But setting that aside, the letter makes it clear that Montfaucon is (or was) a trusted colleague of the author. So it is entirely possible that Montfaucon’s beetle collection CAME from Waldegrave, maybe as a gift.
As always, this is purely theoretical, and I am happy to hear counter-arguments from anyone, but I really think that there is a lot to suggest a deeper connection between these characters.
