It is said that Pokemon can sense the feelings of their trainers.
Yeah, and it's also said by extension that if two Pokemon fall in love, chances are their trainers will too. Well that was refuted in the series. It was also said if two people see a school of Luvdisc, they'll fall in love. So unless Ash is two-timing with Dawn and May, that is also refuted.

Anyway, I hope this pairing starts to get mutual development within the next twenty episodes. A one-sided ship from Serena's end will be rather pointless .
