The conversation between Siger Holmes and his son was perfect. He's such a good blend of supportive but still ever so slightly sociopathic. It all works so well.

I had a real fight with him to find that balance. I started with him being supportive and he just stopped sounding like himself. I decided to come at it from a more 'but of course you can do it, you're awesome what is the problem?' angle and that seemed to work. I sort of feel like he might be under orders from Mummy and is going 'is this supportive how fathers talk? Yes, this is totally how they talk'.

I'm not sure if it's just the time period this is set in, but Trevelyan is actually less confident in this AU than he is in the regular one. Perhaps Mycroft didn't do too bad a job stepping in as Father. Or maybe it's just been a bad night for him.

Thanks for commenting! I'm glad you enjoyed it.
