Witnessed my partners first seizure.. Help.

Hi guys, I am obviously new here.. and no offence, but really do not want to be here. My partner has had epilepsy since the age of 8. Had one fit when he was eight, and then three when he was 15, and was on medication from 8-15. He is now 23 and hadn't had any fits since this Saturday. That is where my story begins.. So, the past two weeks my partner has been ever so tired and different? He has had a lot of absences, which isn't that uncommon, but unbelievably tired!! We all assumed he had a bug, as he was a bit sniffly - but he didn't seem too bad. Then Saturday morning comes. He wakes up, a bit dazed and tired. Drops a money jar and breaks it that he has had for years and drops a cereal bowl. Again, Dropping things isn't that uncommon for him as he normally is quite clumsy. I came in to the kitchen just as he dropped the second item (bowl), in which contained dry cereal. As I was just about to say to him to sit down and relax and id clean it up, i looked at his face and he went bright purple. His jaw started gurning, and he stumbled backwards. My first reaction was to get him on the floor safely, as there is a lot of sharp corners in the kitchen. (Therefore, I didn't see if he spat any cereal out.. this bit is important later on..) he then started fitting and his hands went in to a tense clasped claw. The first fit of shakes/trembling lasted around 3 minutes. He then sort of stopped, and was still breathing but wasn't right. Then another 40/50 secs of shaking. He then had a massive gasp of air and was back with us. He wasn't normal by any means. He was absolutely dripping in sweat, dazed and confused, but he didn't wet himself. I obviously whilst this was going on had called the paramedics, who arrived at the end of the seizure and took him to a&e. We was there for around 5+ hours. All his bloods and neurological tests came back normal - so they sent us home. He rested a lot and couldn't really stop sleeping. We had to go back the next morning and be seen again. Again he passed the tests with no problem. They said instead of seeing the neurologist, they would again send him home with a appt to a first fit clinic in 3-4 weeks. He can't drive until then. When he goes to the clinic, he has to have EEG and a MRI. The consultant kept using the word precautionary, and said the referral to first fit clinic was mainly because of his history as a epileptic. This is where the cereal without milk comes in from earlier. When we got home from A&E the cereal that had been spilt before the fit on the floor was moist and all clumped up - almost as if it had been spat out. So we obviously mentioned this to the consultant the next day. She now believes a new theory that he was in fact choking on the dry cereal, and as he has a history of epilepsy, it trigged a seizure (especially as he was tired and unwell). Now i know we won't 100% know until the MRI and EEG, but i am just so concerned. Just looking for experienced peoples opinions/comments. Does it sound like the Epilepsy making a return? or a one off? He is a joiner so needs to drive and climb for work. if it is a one off, will they stop him driving for a year, bearing in mind its been 7-8 years since the last seizure? I know if it is the epilepsy they will suspend his licence for a year, what does he do at the end of the year if fit free? We are so lucky his boss is accommodating and will take him to/from work. So that is a worry gone! Also, What do i do if it happens again. I panicked like mad this time, as i had never seen it?
