I use to be scared when my partner had auras and would start seizing. I could see it in their eyes as if they had drifted away. While they were seizing I'd hug them and speak softly to them that I was here with them, everything will be ok, and we would ride this out together. Sometimes they could hear me and respond despite being a tad disconnected and other times they couldn't respond back, but would squeeze my hand til they returned to their normal selves. I think it depends on the person. My partner wasn't always the one to show emotions, but the seizures made it really difficult and they'd sometimes weep while seizing. When that happens I would wipe their tears away while trying to comfort them.

Also something to note, as soon and I notice my partner begins to seize I would have my partner sit or lay on the couch so they couldn't fall and hurt themselves. In public, I would try to find a place to sit and comfort them while they rode out the seizure. I always kept count of how long the seizures were and making sure nothing abnormal happened. Once you get use to it it's no longer scary and it's comforting for my partner that they know I'm aware what needs to happen when it does. Don't lose hope and hang in there.
