Help! Dyed portion of phalaenopsis is now dead

[sara1234]

Hello!

My boyfriend got me a gorgeous orchid (phalaenopsis) that had been dyed hot pink for valentine's day. It appeared perfectly healthy for the first few days, but then the flowers started to wilt (I'm assuming this is part of their natural cycle).

My main concern is the area where the dye was injected. Over the past few weeks it has gone from what appears to be dead stem right around the injection site to about 2 inches around the whole stem of dead stem. However, the stem appears healthy above the nearest node and also towards the base of the stem. Will this dead injection site eventually affect the entire plant? Is this normal? Should i cut the stem? I have attached pictures. Any help would be greatly appreciated!!
