... Or it could be a mortal cellphone that was used as a plot device to show that Molly is becoming less mortal. Either could be true but I think the second is what was intended/does more to progress the story.
I think Harry sees it as her becoming less human. Less Murphyonic field...
Oh, yeah! Clearly,
Harry is worried about Molly "becoming less human."
The question I was raising was: do we think he's right? Or is this another bit of unreliable-narrator-Harry & Jim's misdirection?
Is Molly carrying & using an
actual cellphone... and therefore using her mortalborn magic vastly less (and favoring her Winter/Mantle powers even when her own magic could have sufficed)... and thus becoming less human?
Or is she using something that looks like a cellphone, operates like one, but is in fact a magical doodad that plays very nicely indeed with her mortal magic?
I note that the pseudo-Harry illusion she provided (that Harry used on the docks, agains Ebenezer) could have been a Molly item without any Winter Lady power at all; or it could have been pure faerie glamour, without any of Molly's mortal magic involved; or it could have been any ratio or blending of the two.
I honestly don't see that we have enough info to make any firm conclusions... hence, I present a WAG and solicit comments from the Paranet(online) hivemind...
:-)
... The field is there or it is not. Hers is dying. Also, the Ordo Lebes seemed able to use modern things. Less power, less interference ...
I think the "murphyonic field" is highly-variable between wizards. As noted, the Ordo Lebes could all mostly / more-or-less use mortal tech, with only minor glitches & failures (n.b. not
none).
Harry reduces his own murphyonic field by staying calm & relaxed. I presume actively meditating would reduce it further. IIRC, he was doing something special (sustaining a spell?) to be "less murphyonic" on the Larry Fowler show.
Thus, one presumes that older and more-disciplined wizards have less troubles.
Also, we know Harry's own magical talents & inherent strengths include big, flashy, extravagant "boom" sorts of things, and that
kind of magic is (we don't know with certainty, but surmise; if only for Jim's own torment-Harry reasons) probably more-murphyonic than subtle things like veils and mind-magic. Jim has said that Molly is in many ways "just as strong" as Harry is, but her subtler magic is
probably less-murphyonic.
