'Looks like her time is thinning out'
Seeing the bloody scene and comparing it with the knowledge that I possess, I could easily guess that Sabrina's situation isn't all that good, in fact, the ability she's using right now is extremely taxing on her, plus the pain she's going through is also inhuman,
'Gotta meet her fast'
Having gotten an idea of what was happening, I quickly moved toward Sabrina's location, as for how I know it? well, the little gift that I gave to Sabrina has a small tracking location, of course, being as smart as she is, she would have checked, double-checked, and even triple-checked the thing I gave her.
Also adding on to her desperation that she hides, in the end, she ended up using my gift, well even if that failed I had several backups in place, one being her most favorite book, one that she cares above all and anything else, the one book signed by her favorite author that changed her life....me.
