Different Marco, Same feeling

Since Marco came back from his interdimensional wild goose chase he came back changed, making changes for the better of himself, although he was still the same "red belted karate safe kid". Being away in another dimension for 16 years and turning into an awesome, ripped, skilled, brave and strong piece of an adventurer and then turning into a 14 year old teenager with the mind of a 30 year old grown man made him different (obviously) in those 16 years he's been thinking about stuff that made him realize about something he felt about his bff Star and something that Star has been hiding from him. Over the years Marco has mastered and acquired many combat skills and abilities especially Flirting.
