Loved this issue (then again, I've been consistently enjoying the series from the start). The moment between Greycrow and Peter was nice. I also liked the consistency in Nanny's more aggressive behaviour after being resurrected - directing this in all areas, including Peter.
I am wondering what will happen when Nanny's secret is discovered. Having an AI on Krakoa will set a ton of stuff off - but will it also cause a dilemma, as it is a mutant AI? Will be interesting!
