Wait aminute! I thought that Nick had spent the night with that Whimsy employee. Okay I checked the strips and its far more implied than anything that has happened with Tip. On 6/25, Nick is having coffee with Whimsyguy and is trying to understand his “reality blindness”. He seems to be considering sex to see if “Honeysuckle” could notice that Nick’s drone body isn’t anatomically correct. The next strip shows them saying goodbye in the morning. It could be that they just talked and drank coffee all night but Sweetheart’s reaction suggested that it was more than that, and as a canine, Sweetheart should be able to smell enough to know the truth.
