We prove that a general cubic in the Hassett divisor C₁₄ of special cubic fourfolds of discriminant $14$ contains a non-minimal K3 surface of degree $10$ containing two skew $(-1)$-lines and contained in a smooth quadric hypersurface Q⁴⊆ P⁵, but not contained in any other (possibly of lower rank) quadric hypersurface.
