It's easy to see how distressed Ginia feels as she tries to explain. Even without hearing a voice or its tone, just the way her eyes look, and the way she slowly signs a bit less steady.. That's enough in itself. And even without details, even with just Ginia saying 'people died because of me' and leaving it at that - and Minako not being insensitive enough to ask her to further dig into that - it's obvious this isn't just some small bad thing. It's big. Just listening to it makes it feel like her stomach is sinking inside of her.

But that feeling isn't just due to the realisation of the scope of the bad things Ginia has been involved in. It's also just due to the other's emotion. Minako isn't the type of person who can see someone feeling so helpless and be totally unaffected by it.

".. It must've been hard, right? Living with those memories." She has no idea for how long Ginia has already known about those things, but even a small time of knowing you caused people's deaths can't be easy. Especially if you seem to regret it, or at the very least aren't okay with it - which is why Minako doesn't seem angry with Ginia, more just thoughtful with some sympathy in her eyes.
