It was just a drunken mistake during the stag night, but it moved John to the bedroom of Sherlock's mind palace and now, Sherlock can't think … and John notices.

Simon wasn't prepared for this. So he'd started to beg silently, desperately ... constantly.

Something is lurking in the dark, preying on time itself. Jack has no time to worry about that, though, or about Owen's behaviour or Ianto's empathy playing havoc, because an old enemy of Torchwood One returns, forcing Torchwood and UNIT to stand united. Not an alliance easily forged with, since UNIT is endangering not only Torchwood's existence, but also Ianto's personal freedom.

The very thought of the Rift alert going off right now actually hurt.

Merges between anchors and empaths don't happen accidentally. Sherlock and John know that … until they come out of a traumatic experience merged for life.

John might not be entirely straight and Sherlock might not be entirely adverse to relationships. It's too bad they insist on being just that, though … until they can't, and they have to decide between walking away for good or adjusting.

Sherlock didn't teach John to dance for his wedding. In fact, they learned to dance together much earlier – for a case. Or: The one where Sherlock taught John how to follow and John taught Sherlock how to lead.

"Do you want to hold her?" John asked. Sherlock took a step back, clenching his hands to fists in his pockets ... and wondered why he was scared.

In order to solve a case, Sherlock goes too far, risking his life. To him, that seems quite acceptable considering the circumstances. He really doesn't see why John would be hurt by his actions.

John sighed deeply and rubbed his face, making a conscious effort to relax. Maybe he shouldn't have wished for his life to become a bit more exciting again if this was what he got out of it.
