Ugh, I can't wait until Wednesday. I just thought of the best way to handle a specific scene in my fic and I'm super excited to write about it. I even took time away from my monster of an assignment and filled a text file with details

It'll be my nice little bit of fluff after such a stupidly grueling week (though this scene enters the fic much later, so don't go expecting it soon, readers).
I just want to note...going through ME1's dialogue when encountering Tali (and in Udina's office afterward), there's a lot of craziness and just...condensed dialogue. Like they thought they were out of time and just decided to put out as much information as possible, despite the awkwardness. I'm having a lot of fun wondering how to make that a lot more organic. I mean, how the hell would there just so happen to be information on geth-based religious beliefs on the data core, and info on how the reapers seriously wrecked the protheans? Honestly. How?
And when Shep and Tali meet and she askes who Shep is, Shep is all "Oh Hey I'm commander shepard and I'm on a quest to take down this evil bad dude durr".
Like, seriously? What?
Anywho, should be fun. Wednesday just can't come soon enough...(stupid stats analysis paper...)
On a side note, a reader brought up in a review of my most recent chapter that my Shep seemed like a bit of a know-it-all. Of course, I disagree, but I come from the point of privilege of knowing my characters on a higher level.
That said, I've been writing a fic that relies on my other origin fic a fair bit for character growth, and I also have to write in a way that accommodates those who haven't read my origin fic. I've looked at my writing so far and have noticed that where my character comes across as a bit...holier-than-thou...is when I'm trying to convey to new readers what pisses off my Shep(not every time I bring up what pisses my Shep off, but it's linked exclusively to this type of material). I feel that maybe I'm being a bit too ham-handed, but I also find it's difficult to tone it down without making the links so subtle that readers probably wouldn't pick up on it (and might just think she's a *****), at least for the reasons I'm conveying.
Normally, I convey these bits of character over a long span of time, but with so many new characters about to be introduced, and with new character growth arcs being prepared that rely on some basic knowledge of my character, it's pivotal I let readers know exactly where my character's at fairly quickly...but in doing so, I risk alienating readers because my writing skills just can't push those kind of implied characteristics subtly at a high level. In short, my ability to make an accurate first impression has been called into question, and I can't shake the feeling that my failure in this regard will lead to less successful and coherent plot arcs going forward due to a dissonance between myself and the readership over who and what my Shepard is.
Any tips on how to handle this? I'm kind of at wit's end, and I don't want end up pushing people away just because I suck at communicating subtly and concisely in a strong sense.
Maybe I'm just tired...sleep is a terrific idea. I think I need one of those.
