Amourshipping has a possible chance to become canon. Here is some of the proof, as it is obvious, Serena has a crush on Ash. Sometimes, Serena starts to blush when speaking to Ash. Serena was also the first female companion who was asked by Ash to join his group. On the XY05, Serena asks Ash if he remembers her from Professer Oak's Summer Camp, that means Serena wanted Ash to recognize her, obviously. On the XY07, there was a flashback of Ash and Serena when they were younger. Serena injured her ankle or knee. Ash came after a Poliwag while watching Serena's injury. Ash wanted to know if she was okay. She replied she wasn't okay, then Ash wrapped a handkerchief on Serena's ankle or knee, wishing it to feel better. Serena lost her grit or gave up. Ash picked up Serena and hugged her, complimenting how she did a good job. Many fans can infer, Ash had a crush on Serena back then.
On the XY13, Penelope promised Ash that if she is victorious, she wanted Ash to come with her and including the word "sweetie". Serena was jealous how Penelope would say a thing like that. Serena got more freaked when Ash lost his battle against Penelope. With her misunderstanding that Penelope was actually a Miss. Penelope, Serena sighed and said something like "that's what she meant!".
On the XY21, when Serena was wearing her Fennekin outfit, everyone was amazed even Ash, who was doing a blank stare. On the XY25, when Ash was about to fall from rock climbing, Serena got worried about him.
On the XY26, Serena was blushing very hard when Millefeui said something like "Hurry up, you don't want to keep Ash waiting" or "I'm going to steal Ash from you if you don't go".
