This is just a temporary happenstance: with so many level 20 characters in Foggy Bottom, someone will surely resurrect him soon...
Well, failing to provide the necessary information on first turn activities, we'll once again run a fight between the Lazy One and Alfred. The previous Lazy One failed to kill him in one turn and Alfred moved away, but let's say Alfred was to busy trying to worry about who tried to assassinate him using 9th level spells because he had more important things to do, like changing Rufus's litter for example.
A few days later, when somehow the Lazy One had bothered to prepare for a new attempt on Alfred's life...
Round 1 :
Lazy Copy casts subtle dispel, hidden under a rock, to remove the magics on Butler 432.
Lazy One casts subtle dispel, hidden under another rock, to remove the magics on Alfred.
DMM does nothing.
Let's suppose that Team Lazy is lucky and succeed in Dispelling Butler 432 AND the Contingency on Alfred (and the five Light Cantrips on his staff). Even if he would be a fool not to notice the advance alert system of five light cantrips going out at the same time -- it was a standard measure among wizards able to cast spells of the 6th level to have a few lights around them to know when their Contingency was dispelled, and also among wizards able to cast only 5th level spells but who wanted other to think they had reached a higher pinnacle of power -- it would be totally improbable that he wouldn't notice his butler suddenly vanishing out of existence.
On his turn, Alfred has no idea of who is attacking him. It could be a Cleric sending Divine Intervention at him. It could be the Head Librarian of Candlekeep Wishing harm to him because he's late returning Journey to Bliss, by Binky, and the ladies are very insistent he gets the book back for loan, it could be anything... But the most probable threat would be that drow matron mother in the distance. Maybe Eilirilia didn't like being dumped and resolved to avenge her... He should have sent a few chocolates for her birthday after leaving. But, it's strange that the chose to act now, and, as a Wizard, he wanted to have time an exert his Intelligence at solving the problem. So, he acted, by casting Dimension Door to appear right behind the DMM (since she was expected to be part of the fight, she can't be really farther as she lacks any mean of fast transportation).
Round 2 :
As they have absolutely no way to know whether the Contingency have been dispelled, Team Lazy, certain they can't be detected, just recast their Dispelling, making sure in their mind that they got their success. It was all part of the strategy exposed so far by the OP in post #670. I suppose that Alfred is still within range of Extended Dispel, eventually after a move action. The DMM does nothing (or maybe she could cast a spell... but nothing that could kill Alfred in one round, since her best offensive ability is harm, which inflicts at most -84 HP. In this case...
At this point, Alfred casts Wish to create a Simulacrum of the DMM (which would cause Butler 432 to vanish, even if he hadn't been dispelled. Telepathically, he instructs his nifty new Eilirilia doll -- Alfred is an ethical man, please don't imagine anything! -- who will act just after him in the initiative order, to cast Planeshift to a harmless plane. Let's say Mechanus, for laugh's sake.
Round 3 :
I don't know what Team Lazy will do (maybe the OP will want to determine actions on Round 3, but on this round, Alfred will demiplane back to his lab, where he will proceed to ask the DMM's simulacrum, who his loyal to him and have witnessed all the habits of the Lazy One and is very well acquainted to him, to reveal everything while he prepares his counterstrike.
