Tim doesn't want to say that the responsibility lies with him, because it doesn't, but that's because Elias is using responsibility like fault rather than cause. Tim's death is entirely his fault, and he owns that. He went to that place and he pressed that button and he took those bastards with him. But Elias constructed the elements in such a way to get them there, and he won't hear word one any other way.

"We had a lovely chat about a lot of things that I missed, yes," Tim says. There's no point in hedging about it. The conversation had been like pulling teeth, but Tim feels more steady about things now.
