Not sure if this one has been fixed already so just ignore if it has.
If you do 'show plate to shadowraith', SW will 'see' the magic as well as the person doing the showing, not as well as he would see it.
To explain, if a tinker with 0% detect is showing a plate to a mage with 100% detect the mage will not see any magic on the plate. If the mage shows the tinker, the tinker will see everything.
Unless of course that's already been fixed
If you say plz because it is shorter than please, then I will say no because it is shorter then yes.
