Using the Sherwood-relics reionization simulations and a WEAVE-QSO survey configuration, we generate mock spectra in four redshift bins, $z=4.0,4.2,4.4,$ and $4.6$, in which relic ionization and temperature fluctuations from patchy hydrogen reionization enhance the Ly$\\alpha$ forest power spectrum on large scales (i.e., at wavenumber $k\\sim 10^{-3},\\mathrm{s\\,km^{-1}}$).
