"Is there an easy way to tell?" 

"They only receive the most recent and most important memories on the first scan," she says, "So if you can think of something not particularly stand-out to ask that you know the other person will know, a shifter likely will not."

"Could we perform the test with non-personal information? Or they get pop culture as well?"

She smiles at him, "Pop culture is an excellent idea!" She tells him, "It often takes them even longer to fully understand the local culture than to decipher the memories of the individual they are replacing. All of that background information, which hardly registers to the average person - references from films, lyrics from popular songs - it all makes excellent material." 

"Oooh, Henry can rant how scientifically inaccurate a show is."

"You guys like scifi?" Robin asks, "Or, watch it, at least? Which ones?" 

"Henry rants about Fantasy shows, because he likes missing the point, but he likes scifi too."

"I only watch fantasy shows because you put them on, and I don't rant about them... much. But I like scifi..."

Scout 15 shadows Soren and appears to feel shy under scrutiny.

Felix tries his best friendly smile, but notices that the shifter doesn't want to talk. "How did you two meet?"

"My guest came to me and requested Sanctuary. Once I had learned of the force they fled, I felt honour bound to offer it." 

"They're fleeing their... Collective? Is that what the shapeshifters are called?"

"Yes. To choose to leave such a group when it is all one has ever known takes a great deal of courage." 

He speaks from personal experience. 

"I am pleased to assist," he directs a gentle look at the being hovering behind him. 

Then he looks back to his unexpected allies, "But this place has been compromised, and it would be quite simple to discover the location of my home, were we to retreat there. Would you be willing to assist?" 

Erin looks to the others for their opinions, "We were going to meet back at my house after we were done looking into things," she says, "I don't mind if you come along. Safety in numbers, right?"

He certainly doesn't mind. He has some questions he'd love to have answered, for both Soren and the shifter. 

So do the twins. Well, so does Felix, Fenris is his usual quiet self.

"Should we get moving? Is there anything to retrieve from here?"

Soren tilts his head, "No, I keep nothing personal where it might be easily found." 

"Alright, let's get going, then." 

They exit the dojo and head towards the upscale residential area where Erin lives. The others will be coming from another direction, so it's unlikely they'll run into them on the way. 

With shapeshifters in play, there's no knowing if someone around around them might be one. They try to stick to side streets away from large crowds, but they can't avoid a few passers-by here and there. Hopefully their new location doesn't get back to the Collective. 

Eventually they come to the edges of her parents' property. Erin leads them to the gate, rather than over the fence, scanning her passkey to get past the simple security. Or, at least, it was simple yesterday; she's not sure she wants to test it now. 

It takes about half a minute to cross the lawn, and then she lets herself and her guests in. 

The buzzer rings just as she enters the front hall. When she answers it, Robin's voice comes through, "Hey, its us, let us in?"

After they'd finished their lunch and conversation (which had devolved into a discussion of sci fi and fantasy by the end), Robin, Jamie and their guests had waved Gran goodbye and made their way to Erin's house. 

Robin leads the way up the path to the front door, where Erin lets them in. 

"Oh, hey, Master Soren. I guess they were right, then? You actually are an alien?"

As Soren nods, Erin gestures them all inside, "Let's grab some snacks, sit somewhere, and compare notes?" She suggests. 

"That sounds splendid."

Snacks are grabbed (Jamie and Robin abstain), and Erin leads everyone to the rec room. The room is only slightly messy - the futon is still out, and they didn't make it before they left - but nothing she can't fix quickly. After she folds it back into a couch she settles on it, Jamie and Robin bracketing her. Caine chooses one of the chairs, leaving the other two, another couch, and a trio of beanbags.

"So. Summaries?" 

"From what point. After we left his apartment." He waves at Caine. "Jamie, Henry and I went to Robin's grand mother. We talked to her for a bit. Mostly nerd stuff because the aliens don't know nerd stuff."

"Yeah! So we can do secret passcodes! Well, sort of. Actually, not at all, Gran said recent and stand-out stuff they get before anything else. But if we think someone's been replaced by a shifter we just have to start talking about star trek or something and they won't know what's going on at all!" 

"Also, she explained the psychic thing. Apparently my mom was an alien? And they're all psychic, and some of them have other powers too. She thinks those times I moved too quickly were in the 'other powers' area."

"We should investigate that at some point. Your powers that is. Meanwhile, Fenris, Erin, Caine and I went to Soren's dojo and found ourselves in the middle of a war zone."
