ALRIGHT I GOT AN IDEA AFTER I READ YOUR GHOST S/O POST. Like since the s/o is a ghost she doesn't have to sleep. But Fell does. Even though it's not a lot he still needs rest. BUT what if Fell finally crashed (because that boy works too hard oml) and someone out to kill him (because i feel like he'd have at least ONE hit out on him lol) managed to dodge his traps and get into the house. The s/o KNOWS when someone is in her house. So she uses her ghost powers to silently follow them. (1/?)
Dude omg Fell would probably pretend that never happened and recalibrate his traps. His traps are impenetrable, how could an enemy get past them?! His pride is pretty wounded lol. He thanks his S/O though and wonders how to take them out of the house so he could bring them along to battles.
