1. Cosmic Lake/Luke will only tolerate his Canon counterpart if he follows the rules and doesn't hurt Chayanne. So he makes sure to lay down the law when he first meets Lake. Not only is their height difference highlighted but also the fact that Cosmic Lake's design is more elaborate and showy than OG!Lake.

2. A more dynamic version of Cosmic Lake's poster.

3. Cosmic Haiden/Ewan and Chayanne have a close call when Cosmic Lake/Luke gets a little too close to their hiding place.

4. In the calmer and more slow days/nights Cosmic Lake/Luke will often build a blanket fort/nest in his room for Chayanne to get some sleep. During which he will stand guard over her to ensure her slumber is peaceful, he has been known to growl at people who get too close. There was even an incident when a technician got sent to the hospital with a broken arm because he didn't listen to the multiple warnings to stay away from the duo, and got way too close for Cosmic Lake to tolerate their continued existence near Chayanne.

5. Luke played the violin when he was alive and that carried over when he became Cosmic Lake, so he'll often perform a violin piece instead of singing and none of the technicians or engineers know how he can do so.
