Can't wait for tomorrow! I'm going to go ahead and call it that Thaddeus saves Maximus, gets really ****ed up doing it, and is saved by the super mutants at the end of the episode, or he accidentally draws the deathclaws to all the Freesiders. Also, I think Coop finds his family but leaves them in cryo, not wanting his wife and daughter to have to live in the wasteland. Finally, Lucy puts the mind control chip on her dad.

Ok just got though rewatch of the S2:E1 and Hank is definitely reaching out to Mr. House

No. He says, "...where you all left off." in that message. House worked alone. I think he's actually talking to The Enclave, and the vault he's in is an Enclave vault. That's why it isn't built like the others, and it would explain why Welch's head is there. It also explains his commentary on different vaults making progress on different aspects of the mind control device, because The Enclave seems to be the group actually running Vault-Tec and the experiments. He also probably wouldn't need to go to Global Comms to contact House.

ETA Although the thing on her head is the same thing house was wearing to interface with his computer, so maybe it is him and he captured and used Welch. I will think it's The Enclave and they're using tech they got from House though.

I think the "all" is the vaults he had access to do the research.

Ok I just went back and here are his quotes from the clip that support whey I think it is him he is reaching out to.

"Nobody in Vault-Tec knows I am here....know much of anything anymore....I don/t doubt you are alive...you spent so much time calculating how to survive all possible contingencies...I am in Vegas these days, back in your old stomping grounds, actually...trying to pick up where you all left off. He then goes to talk about the mind control chips.

I think the comment about old stomping grounds, calculations, and the control chips are key

Could be the president or Enclave leadership. They also did all of those things. Hank also seemed especially interested in the chip when House's double brought it to Vault-Tec. IMO the twist is that the cold fusion diode was always going to The Enclave. It could be that it's House, since he tells the Ghoul that everyone works for him eventually, but I think maybe he was working for The Enclave the whole time. He seems to know a lot more about the vaults and the experiments than he should for just being Barb's assistant.

Also, the 31'ers were going to contact the investors using the equipment Norm was using to try to contact Hank or Lucy. I think that's a line to The Enclave, and they're the ones who have always been running the show.
