Aazealh said:Uhhh, no. She just could feel him with her Brand. While it's likely not something the God Hand intended, we've seen that the Brand allows those who carry it to feel the presence of evil and other supernatural beings with surprising accuracy. See for example how Guts could tell Flora was a witch upon seeing her, but also knew she wasn't evil. So Casca, while she was insane, could recognize her son instinctively as a mother through that particular sensation.
If that's the case, why Guts don't recognise him? He has been in contact with his son plenty of time before (probably even more than Casca), and he's way more familiar with the brand than Casca. In fact I don't recall at any point Guts noticing any reaction from his brand coming from his son's current form.
The pain she feel at this time and the amount/way the blood was dripping from the brand was clearly the same as when Guts faced Griffith in the black swordmans arc, just toned down. I highly doubt she could have recognised her son in that.Aazealh said:That's why she could tell it was him even when Griffith showed up in volume 22
