Ian:
This guy is going to have a picnic all planned out for you two. He's found a great spot on a hill, under a tree, and all your favorite lunch time foods! You know he's got something planned too, when you see he's brought his staff. After lunch, you two cuddle up under the tree and he puts on his own fireworks show! Later that night, your families get together at the Lightfoot house to watch fireworks together.
Barley:
This guys is all about the fireworks! You both spent the last few weeks going around collecting different fireworks while he was planning out the best line up to impress you and your family that's visiting. While Colt man's the barbecue, Barley spends time with you and your family, occasionally making funny faces for your younger nieces and nephews. Later that night, after the fireworks are over, Barley takes you into the backyard where Ian makes your own private fireworks for you two to enjoy with each other since Barley had been busy before.
Happy 4th of July everyone! Sorry this is a little slapped together but I had to share my head cannon lol.
