So I was assigned in the plan that I should lure annie to the town under the walls
Since I told them that annie had feelings for me but I rejected it and angela was kinda surprised at the name
Annie but I dunno why so I went to wall Sina with the others to the palace (where Angela's parents coffin is) so I wait outside the palace till the military police along with Annie arrived I called her name and then she started to act a bit strange so I asked her if we can go somewhere and tell her something and as always she might think that I would confess my feelings to her but NO because she is the female Titan and a traitor
So she found out I was luring her to the underground town with eren and mikasa then she started laughing like a choking animal and then she said "you've already got your bet armin now let me have my bet!" She said as she was about to bite her arm then I shot the flare and then the plan worked but not that much and then I saw her wearing a ring with a sharp end this can only mean one thing........then mikasa grabbed me and eren downstairs as the time she cut herself she became the female Titan I knew it then eren tried turning himself to a titan but it didn't work so I just went along with the plan without eren and when I came outside I was too late Serena became the female skeletal titan and tried to kill but she didn't succeeded but then eren finally managed to become a titan and killed Annie but he almost lost then I saw angela fighting it she cut her multiple times she cut her knees,legs,hands,arms,feet and her face but then Annie grabbed her and she was handing her to bernard?! Bernard was also there and then was about to devour her then I tried to stop him but I failed I saw her being devoured my whole world ended as Annie grabbed me so I cut her arm and started chasing bernard as he was about to exit wall Sina i cut his legs to stop him and keep on cutting him
And I didn't care if he is dead and then I saw it bernard was in a crystal with angela holding hands so I started getting out of control so I cut the crystal into pieces and then I grabbed angela and starting crying but I checked her then she is still breathing and her heartbeat is still functioning so I brought her room and asked one of the doctors to fix her and she was fine but she is in a coma for 3 months and that was the last time I saw her I'd wish she will still stay alive
