Ash meant himself, if he meant everyone he wouldn't have blushed along with Lillie.
The fanart has Ash hugging Lillie while Lillie is blushing in embarassment.
Actually Ash hugging Lillie made him want to protect her even more. While you don't even see Ash react to Serena being pulled in, which makes the scene inaccurate because the real Ash would never do that,
>>45278326He actually didn't remember it, so... you basically have to take everything she imagined at face value which isn't a good idea seeing how she has some love disorder. At this point, Ash prefers Lillie in the present and Serena is just the past he didn't quite remember.
