• nothing came to her mind = nothing came to mind (without the "her", is the idiomatic expression)
• he knew she always carries something = he knew she always carried

• your kind trendy advices = Advice is one of those words that has a strange plural. That is to say, you either say "advice" in singular (so "your kind, trendy advice") or you add "pieces of..." in front (like so: "your kind, trendy, pieces of advice"). This is because it's an uncountable noun, if you wish to inform yourself of the other uncountable nouns on the internet :D
• firing on them = "firing at them" would be more fitting
• whit = with, typo

• Make a run = to make a run for it is the idiom o/
• She was way up to try their luck = Je suis pas 100% sûre de ce que tu veux dire. Je crois que c'est un truc du genre (je vais le dire en anglais parce que j'ai aucune idée comment dire en français): "To be up for something" + "To try your luck" mashed together ? Since mixing idioms usually leads to confusion (in my experience at least), I'd suggest either separating this into two sentences like "Trying their luck ? She was up for that !" or to say "She was up for trying their luck" to minimize the change of idioms (= those damned phrases don't give you any space for literary creativity, booouh).

• Unknown rushed = Where to ? In this context, the verb "to rush" requires a bit more information. For example, you can say: "Unknown rushed to the car" or "Unknown rushed to reach the other side of the cabin"
• [...] remain as a team. = You can say "We should do this as a team" or you can say "We should remain a team". But when you say "as a" you imply you're going to perform an action, while "remaining a team" is something passive.

• begun = began (Began is the past tense, while begun is the past participle. So basically if you just have a past tense, you use began, while if there is have/had/has in front of the verb to begin, you use begun.)

• Was he giving it up to her = Was he leaving it up to her (= Leaving something up to someone is the expression °^° In the sense of "he is letting her choose")
• Let's say it was = Let's say she did (you refer back to the last sentence (namely the "she had a point"), so it's: "Let's say she did [have a point he couldn't argue about]" and not "Let's say it was [*have a point he couldn't argue about]". If you want to refer to the point instead, you'd have to change the construction of the sentence preceding it, meaning: "Or at least, it really sounded like the point she made was irrefutable."
• Don't you know what there is at the end of the fields? = With this construction, you're giving the impression Unknown knows what there is at the end of the fields, and she's either surprised Noah doesn't or she is trying to make him guess. For example:

- I wonder if Nano. made cookies last week.
- Don't you know she made a hundred? [ implied: I thought you knew she made a lot! ]

- I think we should head West.
- Don't you know what there is West? [ implied: It's zombies and we'll die if we go there. ]

So, instead you should say something like: "Do you know what there is [...]" which is an inquiry. Here, Unknown would actually ask Noah if he knew, because she has no idea. (She just hopes it's not a cliff!)

• she didn't want that kind of acquaintance = Okay, so, acquaintance isn't wrong per se, but it is very strange here, since it implies more of an introduction, I suppose ? I don't really know how to explain it so I'm going to use two three examples where 'acquaintance' would be more correct to use.

- Hello, my name is Nano.
- Hi, my name is George. It's nice to make your acquaintance.

= It's nice to meet you

- I saw you at the pub with R2D2 last night. Did you just meet?
- Oh no, he's much more than just an acquaintance. We're lovers.

= Someone who you are familiar with, but not closely

- Did you know the Hopi have a different concept of time?
- I wasn't acquainted with that.

= I wasn't aware of that/I did not have that knowledge

So, depending on what you want to say (e.g. Does Unknown not want to shake hands and meet a robot like that ? Or does Unknown not want to be familiar with why it came there and why it shot them ?), you'd have to change the sentence to respectively: [...] she was pretty sure she didn't want to make that kind of acquaintance (with it); or [...] she was pretty sure she didn't want that kind of knowledge/info(rmation) (or even [...] she didn't want to know)

• Well, if we hang around since at least one or two days = Only use the present perfect if you use "since", so: Well, if we have been hanging around since (...)
