"Yeah, well. Like I said."

Once Cal known enough about Jarvis, he'd stopped fitting into that theory.

There are other things too, like how Sherlock clearly doesn't resent Tony the way Cal has seen in (what he thought were) similar situations, or how Tony never seemed to miss who his brother had been, but Cal had kept putting those questions aside when they came up because the answers were none of his business. And besides, in a situation that had gotten bad enough to break Sherlock completely, who can say what reactions are even normal anymore?

So it was still Jarvis who was the biggest question mark. Until now.
