Ehhhh... Tobias was still very reluctant. It weirded him out a bit, and he glanced around the room to see if anyone was trying the spell and looking horrified. Gah, it was weird. Tobias didn't want to be able to know if someone had died in a specific place. That was a sad thing and Tobias didn't deal with sad.

Hm.

Biting his lip nervously but then raised his hand tentatively before speaking. "Mister..." yeah he couldn't remember his name... starting again "... Sir? If you did this somewhere outside or something, wouldn't it like show up loads of red? I mean because of old battlegrounds people might not have discovered yet, from wizards or muggles, or going way back through time loads have people might have died in one area... it's, you know, possible. Does the spell ever like... I don't know... is there a time limit on how long ago the people died before their outlines no longer show?"

Not putting off trying the spell. Not at all. But he was interested anyway.
