She would make a great companion, and who knows, maybe she will be, after Act 1. I have to laugh at the lack of imagination from people complaining about narrative.

Baldur's Gate is a big city. How many companions could be added after Act 1, that would have zero connection to the ship? Hell, it could be that some of them could be connected, but just landed in different locations. The possibility exists, it's too bad that it's ignored. To each their own though. Maybe they have seen Acts 2 and 3, and just can't share their insight, because they don't want to get in trouble or something? Or, they lack the imagination to realize that, once we get out of the limited zone provided by EA, things can, and likely will be, different. The initial party has the tadpole in common, not just because "Origin", but because there needs to be a mechanic to incentivize a wildly varying cast of characters to work together. I picked up on this on Day 1 of EA, and yet, reading through the forums, and even just this topic, it's clear that some still haven't picked up on that, despite all the obvious clues, some of which almost literally slap you in the face.*

I always love the "but everyone's level one" thing. On the one hand, it's a very obvious trope, and while I'd like to avoid that as much as possible, if everyone was at their peak power, these forums would be burning down with "but there's no advancement, so no reason to play". Yeah, some of the stories could be toned down, maybe. However, and this is something that occurred to me as well really early on, it could be even simpler, they're lying. SH could have been chosen for her mission because she wasn't more than an initiate. Wyll's story has some very obvious flaws, when you meet that particular set of goblins. Would a wizard with the Earth Shattering powers that Gale claims to have really have fallen victim to what he fell victim to? A simple playthrough paying attention to Astarion tells a lot, when one steps away from "origin", and pays attention to what's presented, instead of what's assumed.
