We met Lily's paediatrician on Tuesday, Dr Tennakoon. He seems like a nice dude.
Long story short the EEG didn't show anything concerning. We're going to get another one done - a sleep deprived one, to closer mimic the conditions of the first seizure - which Lil thinks it's awesome because she gets to stay up until 10pm watching movies on the iPad (with headphones, so Ossie doesn't get woken up). When I wake her the next morning at 5am we'll see how much she likes it ;)
Apart from that she needs another "99.9% it's nothing, but I just want to make sure" test relating to her birthmarks, but he's said it's entirely likely we wont need to see him again.
The sort of doctor you want is the doctor you don't need to see ;)
Assuming all tests come up normal I reckon we'll just keep doing what we're doing - trying to make sure she doesn't get really exhausted over a few days, don't let her climb high up in trees, and make her wear a stackhat on the bike. A few friends I've spoken to with medical backgrounds have said it's sometimes just a thing that happens once and never again, so hopefully that's it.
