Well, the name of this shipping is going to take a long time to have the entire fandom to decide on. I'm dead set on CremeShipping, and I heven have evidence in the ship naming thread, but trust me on this guys, naming this shipping will be a war.
Anyways, just going to give out some details about Comatose. It's about an infinite time loop that starts with everyone waking up a camp, and someone's death will end the time loop and make it start over again. The other in the pairing will soon to start to remember previous days of the time loop, and with Clemont, who will start to regain his memories later, will work together to save this person from death and end the time loop. I guess that's a basic summary :/ Knowing what Comatose means will help understand this complex plot.
Though, I'm waiting for the anime to get everyone's personality down. Honestly I have a feeling this is going to be the anime's best arc, so I'm going to love to see Serena and Ash pull their way through it.
