Epilogue
"Eight years later" - Evan is working in New York, talking on a cell phone with his mom. He passes by Kayleigh on the street who does a double take as she passes by him, he does the same a moment later but misses her glance. It appears that although they were never together in this timeline, there is still some connection between them.
but they knew each other while they were kids ! so the stroke "It appears that although they were never together in this timeline, there is still some connection between them." is totally uncorrect
