There are many of these moments between Wolf and DS.
Pretty much anytime that Wolf tries to protect DS from harm or supporting her during tough situations.
While the two of them are having a conversation in Nimbasa city, DS brings up the time Wolf kissed her in Opelucid city. Wolf freaks out a little when he realizes that was DS' First Kiss, and that he not only kissed her with no warning in front of everyone, but also that he was currently female at the time. DS assures him that she doesn't mind that he did so, and makes Wolf feel better by telling him about how she felt during the times he saved her from her inner demon in the Dream World and during his Disney Death back at the Pokémon League.
When DS learns that Wolf got heart swapped with Anom, she realizes that this is her chance to help Wolf the same way that he always helps her. However, this is easier said than done since they can't spend much time with each other around the others in the group (who don't know about the switch) as that might raise suspicions. Despite this, DS decides she can't just do nothing, and sits down next to Wolf-in-Anom, placing a hand on his shoulder. Wolf is very grateful for this small gesture. Later that day, they also manage to sneak away from the group and have a moment to themselves.
When DS accidentally blurts out Anom and Wolf's secret to the group, she refers to Wolf as "the person she loves", much to his surprise. When Wolf asks her about it shortly afterwards, DS confirms that she does love him, much to his delight.
