iirc, carcel took contraceptive because he's worried for ines's health. He doesn't want ines to bare the burden of pregnancy and of childbirth, considering that ines has a weak constitution. He feared that pregnancy would only make her body worse. Childbirth wasn't exactly safe during those period as mortality rate was high.
YOU NEED TO READ THIS FROM THE BEGINNING ALL OVER AGAIN.
Ines gave him those guns because she was worried about him Because Oscar won't leave him alone, and Carcel lives in constant danger because of him.
Ines has never thought about unalive herself since she's been with Carcel.
Carcel takes birth control because Ines had health problems; she was very weak when she had the panic attack and fainted (which is the same thing that was happening to her in this chapter), and that's why he didn't want her to get pregnant... ALL OF THIS IS NOT PRIVILEGED INFORMATION, IT'S ALL IN THE COMIC.
is she trying to prevent herself from kicking herself again w a gun? is that why she collected it? also why did this nigga take birth control anyways, did he ever explain that lol
