Your friend has most likely blinded that BP by pulling off the living caps, so you'll need to be prepared to deal with that. Several keepers have blind BPs in their collections, so it can be done successfully.
Also, if you keep this thread alive and document everything this animal goes through with Vet visits and such, I will link to it every time someone wants to mess around with stuck eye caps...It could save some snake from a similar fate in the future.
