  We derive explicit expressions for a specific subclass of Jackiw-Teitelboim
(JT) gravity bilocal correlators, corresponding to degenerate Virasoro
representations. On the disk, these degenerate correlators are structurally
simple, and they allow us to shed light on the 1/C Schwarzian bilocal
perturbation series. In particular, we prove that the series is asymptotic for
generic weight $h\notin - \mathbb{N}/2$. Inspired by its minimal string
ancestor, we propose an expression for higher genus corrections to the
degenerate correlators. We discuss the extension to the $\mathcal{N}=1$ super
JT model. On the disk, we similarly derive properties of the 1/C
super-Schwarzian perturbation series, which we independently develop as well.
As a byproduct, it is shown that JT supergravity saturates the chaos bound
$\lambda_L = 2\pi/\beta$ at first order in 1/C. We develop the fixed-length
amplitudes of Liouville supergravity at the level of the disk partition
function, the bulk one-point function and the boundary two-point functions. In
particular we compute the minimal superstring fixed length boundary two-point
functions, which limit to the super JT degenerate correlators. We give some
comments on higher topology at the end.
