Your agent, who referred to himself as Y and later—under duress—revealed his birthname as Hector Valaquez, was most helpful to us. After successfully establishing containment on Mr. Valaquez, who now responds quite amicably to SCP-3435, we were able to quickly recover most of the objects you removed from Site-48 on January 7, 2001.
It is unfortunate that SCP-3435 resisted for so long. It made his containment needlessly harsh and later led to the loss of several of his bodily functions, two of which have not returned. Mr. Valaquez now thankfully realizes the danger he posed to society and has happily religated himself to our care.
We hope that one day, soon, you too will realize the error of your ways.
Additionally, I wouldn't attempt to use those "ways" of yours near Boston anytime soon. We've been recovering a number of your people's corpses thanks to our recent attempts to contain their access to Site-48. As you know, we prefer to contain and preserve rather than outright kill; we are not the Coalition, after all.
Be seeing you soon.
Sincerely yours, - E
