>>112685061Well, a few days ago I fucked around with Episode 7, taking screenshots here and there to see how big is Grace's number.
Based on my observation, the hand can fit at 6 digits (front and back), and each row in arm can fit 8 digits (3 on front and back, 1 on each side).
In this image (the first row right after the hand is cut off), there's 9 rows of numbers, so there is at least 6 + 9 × 8 = 78 digits, or her number is at least 10^77.
That's a fucking big number, and considering her age, if the number grows linearly she isn't old enough to get those numbers, unless she did some really fucked up shit.
So, I think the number grows exponentially and Grace really fucked up her number.
