Wally has been having issues for some time now and he's going in for bloodwork in the morning. He's been having seizures and attempts to control it have been mixed in effect, so he's going to go in to see if a cause can be identified and all that.
Sigh, something else to have to be concerned about, but hopefully it will be something that is "easy" to deal with and not an indication of something severely wrong in his mind or body.
Fortunately, the seizures are over quickly and he's back to normal rather quickly. His personality or ability to learn and understand have not been affected, which is probably another good sign - or at least I hope it is.
