Why the fuck are we even reading so much into these things. Both of the Amour related things this episode are up to your interpretation.
Where she kissed Ash? Not shown, up to your interpretation. That's why it was hidden.
What Serena meant by making Ash her goal? It could mean being with him, or getting to a point where she is like him. The fact Bonnie and Clemont BOTH smiled leads more evidence to the latter, but still.
