Is Game of Thrones brazen enough to kill off a small child? Um, yeah. Duh. We've seen it countless times. But still, we really weren't expecting to see this pint-sized badass go down during battle.
After surviving the chaos outside Winterfell's walls, she retreats inside with her men as the wight army begins pounding down the doors. Before long a wight giant comes charging in, flinging her tiny body off to the side like a gnat. Though injured, Lyanna pulls herself up and screams as she rushes the giant, who picks up her and squeezes her to death.
But — BUT!!! — before she takes her last breath, she's able to bring the giant down with her by stabbing it directly through its glowing blue eye with her sword. At least she doesn't die in vain . . . until the Night King raises her body from the dead, of course.
