What I never got about the VS is why Kaidan has more interactions (and scenes, maybe?) than Ashley, especially considering Ashley was the more popular choice as VS.
Nah, they have the same number, its just that Ashley has more interactions on the Citadel and Kaidan has more interactions on the Normandy. The difference between them is that Kaidan's writer actually put Kaidan's interactions to better use than Jay did with Ashleys, his are more memorable.
On the interactions, they can actually be very deceiving, since they give the perception that a character has a bigger word count than they actually have in reality, when it's just the characters writer putting the word count to better use. Liara for example, has a fair bit of interactions throughtout the game, well, mostly in the first half, she's mute in the 2nd half except for Thessia, (btw , we need to talk about this 2nd half muteness that happens in ME3), but if you pay attention, you will notice that she actually has the least amount of post-mission auto chat.
Like Jacobs missiosn for example, everyone will have something to say about that mission, except for Liara, who will just give her usual, "Thanks for coming by" dialogue and Vega, who also lacks post-mission auto chat. Her writer basically used all of her word count on interactions, with very little remaining for the auto-chat. This gives the illusion that she has far bigger word count than everyone else, when in reality, it's nearly even, except with Garrus, that dude has a far bigger word count than everyone else, by quite a large margin. After every main missions he repeats the same line in 4-5 different ways, it's hilarious.
Now on to ME3's 2nd half muteness. Anyone else notice how you seem to have so many interactions with the crew pre-coup, but then the number of interactions suddenly fall off a cliff post-coup? I have a theory about why that is, but I just wanted to know if anyone else noticed this. There were times in the 2nd half when I actually forgot that the squadmates existed, even Garrus. Liara is mute until Thessia then is never heard from again, Javik and Vega are mute until Rannoch then are never heard from again, Garrus is mute until post-Thessia and is never heard from again, Ashley is mute until post-Rannoch then is never heard from again, you can see where this is going.
There's a specific point in the 2nd half allocated to each squadmate where you get something from them, then it's bye bye until Priority:Earth. This didn't happen in the 1st half, there was so much interaction with them, then in the 2nd half it's silence until a specific allocated point in the game where you remember that they exist before they go revert back to Zaeed style dialogue, or in Liara's and Vega's cases,"Thanks for coming by" and "Hey" style dialogue.
Like I said I have a theory on why, but it's probably wrong anyway.
