Her last line sounds odd. If she was on the same plane as Hector, wouldn't detecting magic being used on him be easier?

some skilled magic pracitioners can very skillfully cover thier tracks, expecially if it's cross-plane they're already phenominally skilled.

oooh, so its in case the source is on another plane.

Hmmmm.... this is a better plan, follow up both physical and magical possibilities..... considering that both of these are weakness/stress points for Hector.

Had thought it would be a good way to try to mask an attack on Hector.... hide your magical attack in the symptoms of something like liver failure and then let those helping him get sidetracked with the seeming obvious.... especially if the apparent trigger effected others. Of course I am just talking to the wind here..... anything could be happening....
