Toybox is in a pocket dimension, but there is a good enough chance that it has a fail-safe by dumping the contents. If Strider was mid-port --well splat. If that one Accord cape was in the mirror universe --never found. Grey boy victims are suddenly bleeding out all over the place.
And here is a possibility. When he starts the chain for targeting Scion, some of the first spells might have disconnected the shards in ways that caused phasers to unphase (Shadow Stalker), or reform in human form as they stuttered.
