She finds them early

You loiter around the library a little longer, and as the clock ticks towards the nine o'clock opening Emma comes back to the desk, checking her phone as she does.

The moment she see's the text her face turns ghostly white, and you feel momentary panic coming from her. She quickly begins to reply to the text message.

'Who are you? I never took that photo, how did you get it?'

You chuckle to yourself and wonder how long you should make her stew before you reply.
