So since we’re making pacts with the 7 brothers again, do you think it’ll be the same order?
I personally can’t see Mammon making a pact with a stranger while his brothers need him.
I also don’t see Levi being willing to make a pact with some random rn, mans got tons of deep rooted hatred for demons after fighting them for years
But I think it makes the most sense if Mammon's the first because;
• Mammon being MC's first friend/companion/tour guide is consistent throughout different AUs in om! (that we see in events and devilgrams). So it'd be odd if that suddenly breaks off here?
• He's also instantly intrigued by them/interested in them when he meets them as an angel in the celestial realm. I just imagine this is a constant for Mammon?
• Mammon in S3 says he wouldn't make a pact with a random human. Which is exactly what he did in S1 because despite being intrigued by MC at the time he didn't know them. However, S3 also shows that MC wasn't a random human. They travelled back in time to when the brothers were still angels, made a lasting impression on the them (they encourage Mammon's dreams, laugh at his pranks that no one finds funny and according to him they keep staring at him despite being called out twice). And though MC's and the brothers' memories of this time are erased, Michael says that the effect of their presence will be felt. Angel! Asmo & Lucifer also dream of MC though they can't remember who exactly they're missing (which means the others definitely had similar dreams). So then Mammon's decision to make a pact with MC in S1 could have been subconsciously influenced by this encounter (and it was a decision because being much stronger + faster than Levi & MC he could have easily gotten Goldie back without having to make a pact). Nightbringer happens after that encounter in the Celestial Realm. So the impact of that encounter would, realistically, still be felt in Nightbringer. In other words, the brothers may still feel drawn towards MC/feel like they're familiar
• In S1, MC is also instantly comfortable with him (enough to talk back to him over and over again) while they're reserved with the rest of the brothers until right before/after they make the pact. They've also been called out multiple times (in the main storylines or chats or devilgrams or events) for having a bias towards Mammon. Beel in S1 also said that MC had a tendency to seek out Mammon to talk with him. <- MC, themself, might just gravitate towards Mammon without him having to do anything
• They also never register Mammon as a threat, even during circumstances where they should (vampire devilgram, first paws event, s1). They're comfortable enough with him that they start regularly sharing a bedroom in S1 before they're even proper friends. So again, they may just gravitate towards him.
• Like in S1, Mammon might be the only safe option for MC in the beginning. He's clearly the only one who's got his shit together right now, while the others are visibly heavily traumatised. He's the only one with no regrets about his decision/who seems to have come to terms with what happened. It makes less sense for the ones who are Going Through It to make a pact with a random ass human than the one who is actually (considering the circumstances) extremely well adjusted
• MC's being dropped into Nightbringer to be a therapist to the brothers during their worst moment of life. Previously, Mammon's the one who took on this role (as seen in "The Rulebook" Devilgram). As you said Mammon's brothers need him and literally the best thing he can do right now is team up with the person who's also trying to help them in the same manner he is. It makes so much sense for them to be working together towards their common goal from the beginning, than to be at odds with each other until they make a pact later on
• By the process of elimination, Mammon's the only one who's mentally in a place to make a pact right now. AND at this point his brothers see him as extremely competent (because he is) and reliable - someone who can do anything he puts his mind to. After they Fall he's calm and collected, he's the one who talks them down/soothes their injuires and nightmares. They trust him. They'll, therefore, be much more open to making a pact with MC if Mammon already has one, if they feel like Mammon trusts MC.
• Mammon was literally created by the writers to be MC's "sidekick". It'd be weird to suddenly break away from something that was a major defining point during the creation of his character
I don't know what order they'll go in to make the pacts but listen,
I'm not even saying this as someone who's simping for this idiot;
It's just, objectively, it makes much more sense for Mammon to be MC's first pact again, than for any of the others.
