We prove that every Hodge-generic algebraic curve in $\mathcal A_2$ over $\overline{\mathbb Q}$ contains only finitely many points whose abelian surface is isogenous to the square of an elliptic curve without complex multiplication (CM). Combining this result with the companion $E\times\mathrm{CM}$ and quaternionic-division finiteness theorems, we prove the curve case of Zilber–Pink in $\mathcal A_2$ over $\overline{\mathbb Q}$, without a boundary hypothesis.
