I am now working on my reply to the most recent post, and I noticed that the 'shadowy figure' immediately saw that the two were from Fairy Tail. I don't care so much about this because I know it's a plot device, and we could easily say that the figure was informed prior, but Sanguin's guild mark is on her cheek (beneath her mask) and Ben's is on his back (beneath his clothes). Just something to be aware of.
