Data's "blocks" are largely self-imposed and under his conscious control. He doesn't "have trouble with contractions" - he chooses not to use them, just like he chooses to babble, to use big words, and to tilt his head. Except when he chooses differently
How can you say it's a choice & not design? There's no evidence either way, other than his own claim that he believes he is incapable of contractions & emotions. I take him at his word. He genuinely believes he can't do those things, & enough examples of it occur for both him & everyone he knows to accept it, even though we know he can, & other Soong androids do them as a standard.
Clearly, he's been deprived of function, as we're shown with his dreaming function. It's not much of a leap to think that the guy who buried a dreaming program in him, to be unlocked over a growth period, might also do the same thing with limiting emotional & language function, imho
She never really panics, malfunctions or reacts with too much stress until then.
She never really has any reason to. In fact, Haftel literally proves his approach is entirely wrong. He almost instantly proves the best way to raise this youngling is with an experienced kin, since it seemed to have been working, in otherwise uncharted territory, & all went to crap the minute he interfered.
I agree that the admiral's interference had direct catastrophic effects on Lal, but I also think it's possible to see this both ways. The admiral could 've been the catalyst without actually being the cause or flaw. So maybe the faulty matrix Data installed was only faulty in so much as it was a sensitive one, prone to failure when disrupted too greatly, & in this case was related to emotional awareness (Which he only has minimal amounts of himself)
She might've crashed because she was having something happen to her, that the matrix she was cloned from (Data's) doesn't have happen, & it's possible there was something delicate or undeveloped, if not completely faulty, that the admiral's influence exacerbated.
While I agree it's certainly possible that she'd have not crashed if the admiral hadn't come aboard. Something else just as emotionally traumatic COULD have happened. That's life. Stuff like that happens all the time, & either Data created a matrix that couldn't process it... or couldn't process it yet, at this early stage of development, & being that no one was expecting her to be processing it at all, the same outcome was very likely. What if Data died in the line of duty (like he actually did)?
If all it took was an admiral suggesting she be relocated to overwhelm her, any number of other similar catalysts could've done the same thing

Here's an interesting thing I just thought of...
Data: A Klingon Male (In reference to Lal's potential body choices)
Troi:
A friend for Worf.
Are you kidding me, lady? Has Troi ever met a Klingon? What would ever make her think a Soong android masquerading as a Klingon would ever fit in with real Klingons? They're not even all that tolerant of half bred Klingons, or ones living outside the empire, like Worf, & while I doubt any of them could kill Lal, it would clearly be a terrible choice for socialization. That would NOT be a friend for Worf, as if that's even a good reason to choose it anyhow.
Everyone in that room should've been like... "A bloody Klingon? NOOOOOOO!"
