I mean more due to the bit where Samus a) doesn't actually have a mech but a power suit, which would make any gattais awkward as hell, and b) Samus is really not the kind of person who would open even a smidge of her mind to someone she doesn't have absolute comraderie with. Which nobody in the Chalice is even close to yet. I'm pretty sure a mind like a steel ball is not very helpful to spiritual gattais :p.
