Okay so, what would Annie do if she's home by herself and notice that somehow Julius got out?
Oh my god it would be a disaster like. She walks into their room to change into lounge clothes or something and she is faced with the most horrifying sight; an empty cage on their nightstand. Annie just stands there, staring, soul slowly leaving her body as she realizes
1.) That fuzzy creepy ass large ass arachnid ass tarantula fiend is free and roaming around their room, possibly around their house. Crawling on her shit. MOCKING her, somewhere in the shadows
2.) Armin will be home any minute and his precious best friend and faithful familiar is nowhere to be seen and could possibly be in trouble and for the sake of the boy she loves, creepy fucking cursed pets be damned, she has to find Julius and make sure he’s safe. Even if she has to....pick him up herself.
So she equips herself with rubber dish gloves and grabs the cage and a butterfly net, stalking the house and checking in every little corner. Calling out his name. “Juliuuuus. Come out you little agent of satan.”
Eventually she sees him just sort of like. Chilling on the TV, staring at her, and she slowly approaches to try to scoop him back into the case when that little fuzzy bastard jumps on her hand all the way past the gloves and is crawling up her arm.
Annie Leonhardt has never felt the fear of god so much in her entire life. Like, she drops everything in her hands, and is completely frozen in place for fear of...SOMETHING. He’s just chilling on her bicep staring and she is holding back a blood curdling Female Titan style scream when Armin walks in the door
and sees what's happening. Staring just as confused until he breaks out into a big smile because “AW I KNEW YOU’D GET ALONG” and Annie’s just like Put That Thing Back Where It Came From Or So Help Me
