Before they would eventually get to the shrine, Yuki noticed that. His phone got another Future Diary message. It read:

[u]Someone is already at the shrine.[/u]

Yuno saw that Yuki was reading the new entry and peeked at it to see what it had. "Shhh...let's approach quietly..." Yuno whispered to the group, though she still didn't like Inori with them,"Someone might be here already...if something goes wrong, you'll be the decoy..." When she meant decoy, Yuno meant she would leave Inori here to die if something did go wrong. So the closer they got to the shrine, Yuno and Yuki would crouch down behind a bush, and wait for any action from this person at the shrine (Lightning) or see if a new entry comes up.
