Laddy, just trying to get the full picture. How much time elapsed between the pub and being found at home? What sort of injuries were they? Is it a fair assumption that given her condition someone might have escorted her home? Did you leave the pub together? If there wasn't a third party involved by spiking her drink, she must have a medical condition she is unaware of. If you google 'why do I have a blackout' you will see quite a few possibilities.
