Ginny & Georgia fans are even more concerned about Austin being recast in season 4 now that Diesel La Torraca is officially taller than his onscreen sister, Antonia Gentry. Gentry, 28, took to Instagram on Tuesday, October 7, to share photos of her and La Torraca, 14, on set throughout the years. While some found the throwback adorable, others pointed out that La Torraca had clearly aged. Meanwhile, his character on Ginny & Georgia has remained a second grader for three seasons straight.
