Sherlock ran out after John. Sure, Moriarty's reemergence was unexpected and scared him a little, but John's outburst was completely unwarranted.

"John," Sherlock said.

"I am not working a case involving that man," John said quickly, "I am not going through that again."

"It's not going to be like last time," Sherlock assured him.

"You don't know that," John said, shaking his head, "You don't know that and I don't know that. Last time he was involved, you died, Sherlock."

"But I didn't."

"But you did, Sherlock. You were dead to me for two years..." John's voice cracked.

Before Sherlock knew what was happening, John hugged him. This hug felt different than others. No one was dying, it wasn't as happy as at John and Mary's wedding. This hug felt heavy and painful emotionally...for John. Obviously.

Sherlock didn't know what possessed him to do it, but he hugged John back.

When John kept hugging him, Sherlock found that he rather liked the warmth his friend provided. "I'm not going anywhere," he reassured John, "But we should go to your house and warn Mary."

John released Sherlock instantly and stared at him.

"Why my house?" John asked.

"Well, you're still in your pajamas for one thing, but Moriarty's back," Sherlock said, "He tends to attack what I care about, and that's you." John looked at Sherlock for a second but nodded and pulled out his phone.

Sam wandered over presumably to see what was going on as John called Mary.

"We need to go to John's flat," Sherlock said, "If Moriarty stays true to form, he'll probably show himself there."

Sam nodded, "I'll tell the others."

Moments later, they arrived in John's living room. Quite literally in his living room. Mary stared at the phone box in confusion as Sherlock, John, Dean, Castiel, Sam, Gabriel, the Doctor, and River Song all filed out.

"How on earth did you all fit in there? Is that like a clown car or something?" Mary asked. The Doctor held the door open for her to see the spacious interior.

Mary grinned at the Tardis. "It is like a clown car. Nice," she said.

The Doctor sighed and shook his head at which response River patted him on the shoulder sympathetically.

John watched the wonder on Mary's face with such a look of love, Sherlock felt like disappearing right then and there. He was in the way. His friend was married with a child on the way. It would always be Mary before Sherlock. Instead of feeling jealous about something he'd known for a long time, Sherlock resolved his last vow and knew he had to protect Mary no matter what. He cared about Mary, but he had to protect her for John's sake.

"I think we should take Mary with us," Sherlock said.

"What?" John said, "No. We're trying to hunt this thing. It's dangerous."

"I can handle myself, John, thank you," Mary said quickly.

"Mary, I know you are a more than capable person, but you're pregnant. There are limits," John said quietly.

Mary conceded, "Well, at least tell me what's going on. Like where have you been, and why are you in your pajamas?"

"That would be my fault," Sherlock sighed, "I took him on the case last night. I didn't think it would involve the supernatural."

"Oh, I love 'Supernatural!' Brilliant series," Mary said.

"That word was an actual word before it was a book series, you know," Sherlock said quickly.

Sam said exasperatedly, "Thank you! I keep trying to tell people that."

Mary looked at Sam and back at John. "Wait, is that-?" she asked. John nodded, grinning.

Dean sighed, "I'll be in that Tardis. I'm not doing this again."

"Did I miss something?" River asked the Doctor. Sam followed Dean inside. Sherlock noticed John looking at him and was contemplating escaping to the Tardis himself.

Mary went up to Cas and said, "There's just one thing I don't understand."

"Just one?" John asked.

"How did you get Sam out of the cage? You needed the horsemen's rings to get in, and how did you get out if the two most powerful archangels couldn't?" Mary asked.

Gabriel scoffed, "Most powerful. That's debatable."

Castiel looked at Mary and asked, "You want to know how I saved Sam?"

Mary nodded.

He said, "I did it very carefully." Quickly, Cas walked into the Tardis. Mary started to follow after him, but John stopped her.

"He may not want to talk about it," John said, "It isn't just a book series to them."

Mary nodded, understanding.

Sherlock said, "You should get dressed, John. I'll talk to Mary about the angel problem."

John left to get changed.

Sherlock was just able to say, "Moriarty's back," when Dean burst out of the Tardis.

"We've got it!" Dean said.

"Got what?" Gabriel asked.

"A plan," Dean said grinning.

"Really?" the Doctor said, intrigued.

"Purgatory," Dean said, "We can send the angel to Purgatory. That's where all the leviathans went, and we didn't know what to do with them either. If they can't get out, the angel won't be able to either, and I'm sure the other monsters will keep it busy."

"How are we supposed to trap it there?" Sherlock asked.

"Purgatory is a physical place, and we do have a spaceship," Sam said.

The Doctor shook his head. "No, no. I am not having a weeping angel in the Tardis," he said, "It could destroy the universe with that much time at its fingertips. Not happening."

"Wait, do you have my vortex manipulator?" River asked.

The Doctor's eyes widened. "Yes," he said, "Yes!"

John came out in a sweater and jeans. "What are we excited about?" he asked.

"We have a plan!" the Doctor shouted, running into the Tardis.

"How's that now?" Sherlock asked.

River explained, "We can program the vortex manipulator with the coordinates for Purgatory. When we find the angel, we can touch it and send it there. It's just a matter of setting the coordinates and finding a volunteer."

"Volunteer?" John asked.

"Whoever sends the angel there will be sent to Purgatory as well. They can easily get back with the vortex manipulator, but it would still be a rough trip," River explained.

"I'll go," Sam said quickly. Sherlock supposed it made sense that Sam would go considering the Winchester seemed to be pretty physically tough, and Purgatory would probably involve a lot of combat.

The Doctor came out holding the small, wristband shaped trinket. "Who's going?" he asked.

"I am," Dean said, taking the black tool, "You already got stuck there once, Sam, and I know the lay of the place better."

If Sam objected, he kept his opinions to himself.

Sherlock was tempted to volunteer just to be out of the way, but he still had Moriarty to contend with.

"So, how are we going to find the angel?" Sherlock asked. Maybe he could helped with that.

River said, "We'll need bait. Something Moriarty or the angel want."

"Well, what would work for that?" Sam asked.

John said quietly, "Sherlock."

Sherlock looked at John and saw the fear in his friend's eyes and much more concern than he was used to getting.

But he was right.

Sherlock had to be the bait.
