No, thats not called "analytical reading", but it may be called "anal reading" in your case.
Arhu actually says that his Sparkmaster attained a will of his own, a consciousness of his own.
Which, if you could read with anything but your backside, would be very clear to you.
He also never mentions trying to use the controller on it himself - which is another of your anal fabrications.
He actually says he has no time for it - since he is very busy with actually important stuff - which is the reason he gives you the controller.
Opposite of all that, we see a sparkmaster being ridden by some undead. Under their... "control". For some unexplained reason. (i think its just for lulz, btw) Something we never hear about or see before or after that one case.
Which doesnt fit even with your wrong misunderstanding and misinterpretation of Sprkmaster getting "out of control". Naturally you will try to counter this by simply pulling out another invention of "undead being able to control Arhu mechanical contraptions" - which is as useless, incoherent and nonsensical as the rest of your posts and anal logic.
(that would be as in "anal fixation", according to dr. Freud btw, before anyone accuses me of using curse words, mkay?)
I did what you could not, without breaking a sweat, with a lower level party and without abusing the system like you did. Call me a moron, but I'm still tactically better than you at this game.
What you did there is easily and factually confirmed what i said about you previously is really true. And, by the way...to win that encounter - you did abuse the bugs and deficiencies of that encounter. However unwittingly.
