I can imagine it must have been a shock. Tonally, it's a dark enough show for me to believe it might kill off a major character, but it doesn't have that many major characters, so I didn't think it could afford to!

you seemed more invested in Reese and Reese/Finch

Hey, Reese/Zoe and Finch/the Machine is where it's at! (Although I do love Reese and Finch's relationship.)
