Orchid Trilogy: Resurrection - sun burned Phalaenopsis begins new leaf growth

common phalaenopsis orchid begins hearty new leaf growth after one leaf is heavily damaged by sunburn and is discarded by the plant

My phal is looking pretty good, that new leaf is very pretty. The one leaf that was heavily sunburned just yellowed and shriveled up, and now it come completely off as you can see in the lower left.

It's interesting to see the orchid cope with an alteration of its growth pattern due to the disorderly damage my accidental machinations have caused. I'm curious how soon it will drop the other leaf, or if it will keep that one for a while.
