All good things must come to an end, and for Valentia Vostok, her time as Firestorm was an extremely brief one, which is a shame really, for she looked fantastic engulfed in flames. With Jax managing to get Martin Stein to overpower Vostok, Valentina was left to go into meltdown as she didnt have the necessary stability needed to maintain Firestorm on her own. This, again going back to what had been seen previously in The Flash, was much like how Martin Stein himself struggled after he lost Ronnie Raymond last year. At that point, Stein was on deaths door because he couldnt sustain Firestorm on his lonesome, which is where Jax came into play. Unfortunately for Vostok, her demise was a quick one here.
