The issue was more that they needed to identify only the ones that illegally entered the premises, and separate those from people legitimately working there. They then had to cross reference those IMEI/MACs to camera footage of them illegally entering the building. Some of those dipshits were ID’d and picked up immediately, others used burners and covered their faces with masks (ironically) and had to be tracked similarly to how Luigi was caught; establishing a timeline of events with that same individual using other cameras in the area until you find one of them without a mask on.

I could clearly see Ciri’s green eyes at the beginning and at the very end.

She is a Witcher, i believe Triss and Gerald were able to find the mutigen needed in order to do the trial of grasses. In the show it came from Ciri’s elder blood

Im interested to know the timeline too, and if Geralt really did retire with Yen.

I had always assumed Ciri would eventually become a Witcher, given her elder blood and fate tied to Geralt.
