Wait, wait, wait.... could it be: That Ep7's Otto handoff to Nadia is a "flashback" to before she planted it on Kane in Ep6? If that's the case you are implying then I can go along with that theory, for sure.
Don't I have something else I should be doing? Oh yeah, my year end accounting (yuck)... okay, back to the bracelet. 
Jeesh...even I not thought of that shit lmao...Wait, wait, wait.... could it be: That Ep7's Otto handoff to Nadia is a "flashback" to before she planted it on Kane in Ep6? If that's the case you are implying then I can go along with that theory, for sure.
Fuck my life... how the hell did I get into conspiracy theory discussions over a fucking data bracelet?
Possible rather than being 'actual blood'...it's DNA coded and if hers is close enough for her to crack the rest. Refer back to Kwame again...he never mentions blood...just a secure access point matched to a signature. Nadia has the access point (or create one) and if her 'signature' is close enough being related...
No. Nadia's statement that "The only way to unlock the data inside it is with your own blood." Means either A) it opens based on blood type, which is stastically not very secure, or B) it opens based on genetic signature via a blood sample. "Blood relatives" is just a pre-Mendel figure of speech that has persisted in our vocabulary, as siblings and parent-child can have differing blood types. Modern day tests that determine genetic relationship look at the DNA samples of both individuals, and a certain percentage of matching genomes means different degrees of said relationship (i.e. parents, grandparents, cousins, strangers, etc.). However, with the exception of identical twins, siblings genes do not match 100%, in fact, true siblings are tied with mother-child pairings of only matching 50% of genes on average (father-child averages 47.5% match). So, Nadia and Callista have equal chances of opening the bracelet, but if it's specifically keyed to Kane's genetic code, then only he can open it.
Best hacker in the world remember.
Kwamie doesn't, but Nadia does:
Yeah...would Nadia be non-scientific enough to use the world blood as opposed to signature? (which could be blood, saliva, hair), anything you can get DNA from?
Nadia says that she had just did in a few hours what DS couldn't do in over 20 years, and Otto comments previously that it was "a great thing... Everyone is very excited and you deserve all the credit" and that she's "done a lot to help the family." Considering we know how good of a hacker she is, this is clearly her locating her uncle/father Cole the night before, "a few hours" after arriving at JF. Otto will also say that [Dom]Kane is "at least K7", and since Kane is K6 the last time he saw the bracelet, I'm sorry, but it can't be a flashback, but I see where your mind was going there, because it made sense to me once upon a time.Wait, wait, wait.... could it be: That Ep7's Otto handoff to Nadia is a "flashback" to before she planted it on Kane in Ep6?

I mean she kind of already did:
Damn, valid point. Welp, Tess is going to have one helluva time explaining all this... even if there are a hundred bracelets in the wild... there has to be significance in Otto handing one off to Nadia in the scene, it being a one-off scene is a curve ball that otherwise doesn't justify the GPU resources to render the scene's bracelet images tbh.
I posted about it to Tess in her discord (in the feedback channel), so she should be aware of it. If there's any reaction from her, I'll post it here.
IIRC, this scene also plays out on the sub path too...
if subk7 or k7 or k8 or k9:
scene e7nroom18 with mediumdissolve
otto "He's moved up to at least K7 now...he seems to be doing well."
nad "Yes, he's showing the Karlssons what kind of man he could be! But what now?"
jump blockchain
elif True:
scene e7nroom19 with mediumdissolve
otto "[pname] has not reached K7 in the program, and I'm not sure he's going to anytime soon."
nad "Oh, so what now?"
jump blockchainI'll die lauging if she says something along the lines of what I did
Another valid point which (at this point of all the accumulated evidence) makes our entire discussion regarding bracelets null and void. There's too many dialogue bugs in the VN to rely on details for theory...imo.
That...or the same principle of Nadia getting still applies. After all, Kane didn't unlock did he? In fact...he had it for half a day before 'losing' it....
I vote on the latter... she showed favorably at the time Kane saved Reyes if memory serves.
I've also had another crazy (or maybe not so) thought. Following on from the above:
ky "Otto. I'm sorry, but I can't just stand by and let this happen. We need to work on a solution that keeps him here."
ky "His work is best done right on this spot...and this is more important than anything else."
scene e8js29 with mediumdissolve
otto "You realize if I don't try to return with Cole...peace might be gone right away as it is..."
ky "Maybe. But a little extra undisturbed work for him...even a single day...a few days...a week...might make all the difference."
ky "Even an extra small window of time here could result in a breakthrough..."
scene e8js30 with mediumdissolveNo idea myself, when given chance I always do save her....lemme check script.
Veronica's such a manipulative lying bitch. "If you had turned down the game show, you would be farther along with me on that issue."
