Garrett: "So, no one else knows you're here but me?"
Hanna: "Well, I left a note for my mom in case anything happened to us."
Aria: "Did you really leave a note for your mom?"

Because they have apparently switched bodies, Spencer is now the Hanna and Hanna is now the Spencer, because what Spencer is doing is wandering into the creepy empty church and calling out into the echoes and scariness and generally just looking to get beaten to death by the killer or Ian or whoever.
Meanwhile, in the forest, Ian shows up and Garrett pulls a gun on him, but it's not Ian again, it's the new character that the fans voted to name Logan Reed. (No, I am not kidding, there was a poll and "Logan Reed" won, despite sounding like everybody who ever raped a nurse on General Hospital in the 1970s).

Spencer: "Oh hey, Ian. I just got in a massive car accident with your wife and baby."
Ian: "Yeah, I know."
Spencer: "Really? Because I thought maybe you'd want to be there. At least until you find out if your baby is okay."
Ian: "No, I was just waiting for you to leave the hospital so I could come and kill you."
Spencer: "See, problem right there."
Ian: "No, Melissa would want me to kill you, trust me."
Spencer: "Like you killed Alison?"
