Normally she could get Thameslink to SPILL and walk across to King's

plenty of time to get the 23:58 to Bishop's Stortford.

But will her through rail ticket be accepted on the bus if the tube
isn't running?

Erm, dunno, but the worst case scenario is a £2.20 bus fare....? (or
£1.30 with Oyster)

There's the 149 and 48 as bus options too.
