I often think about how the KGB controlled Eliza, and it wasn’t easy. She was dangerous even when she was young — incredibly smart && unpredictable if they didn’t keep her in check. So, they put an inhibitor in the base of her spine, hidden so deep you’d need surgery to even find it. If she ever tried to mess with it, it would hit her with electric shocks bad enough to drop her instantly.
And that still wasn’t enough for them. When they sent her out on missions, she wore a stealth suit — all tactical and black, with a mask akin to the winter soldier’s. But the real kicker was the earpiece within the mask. they built in a micro sonic cannon, and if she ever disobeyed, they could trigger it remotely and knock her out before she even knew what was happening.
but the thing is, she didn’t often need controlling. Eliza grew up inside four walls. She was trained to be loyal to Russia before she even knew what loyalty meant. These were more precautions a means to control the beast within.
