Eva

Eva is Alex and Albert's third child and considered a miracle by the family. More children do not survive than do, and considering the difficulties prior to and during the birth everyone was expecting another stillborn. Fortunately Kyle was spending the summer with the Weskers at the time and managed to convince them to let him take them to an actual hospital. Eva was born safely and fully bonded to the viruses from her parents.

As the baby of the family, Eva enjoys the love of her older siblings and Kyle, whom she also considers a big brother. She's a happy girl who so far only manifests speed and strength from her viruses. If she has any unique powers they have yet to manifest. She is the only member of the family who gets to get away with calling William "Willy".
