\label{fig:mesa} Ages for a suite of MESA stellar evolution models for stars of different masses, incremented by $0.01 \ M_\odot$. masses.  Color indicates the evolutionary state of each a  star as it moves from the Main Sequence (MS) $\rightarrow$ Red Giant Branch (RGB) $\rightarrow$ Secondary Red Clump/Horizontal Branch (HB) $\rightarrow$ Asymptotic Giant Branch and beyond (AGB+). Two nearly-overlapping lines \revise{Lines of constant radius  corresponding to $R_1$ and $R_2$ that fall within  the radius of each star one-sigma errors in mass  are shown (solid black, $R_1 = 7.90 \ R_\odot$; dashed white, $R_2 = 8.33 \ R_\odot$), along with vertical lines corresponding to $M_1 = 2.16 (white, $R_1$ between $2.163$ and $2.177  \ M_\odot$ M_\odot$; gray, $R_2$ between $2.141$  and $M_2 = 2.14 $2.155  \ M_\odot$. This suggests the stars in KIC 9246715 are both on the RGB, because they would need larger radii to be on the HB. Given M_\odot$) for two different values of  the uncertainty in mass (0.03--0.04 $M_\odot$), \revise{which is illustrated with horizontal error bars}, it mixing-length parameter ($\alpha = 2$, bottom; $\alpha = 2.5$, top). It  is possible for both stars in KIC 9246715  to be the same age on either the RGB or HB, depending on  the RGB. mixing-length parameter chosen.}
