If I had to guess who Quince was sensing, it would either be Majin Eve, possibly Amber or Elarinya, but most likely Elarinya since it looks like she's closest on the map to where your character was =)
I think, correct me if i'm wrong, Elarinya stated in the post that she masked her ki as a defense measure due to being in an "unknown area"
Not trying to backseat-gm, I just don't know if that effects Quince's ability to sense her or not, just pointing this out. ^_^
EDIT:
ALSO, i just realized/wondered, will Shadrok be able to see Gohan's tail upon arrival to their location?
