*rattling the bars of my cage* Yes, hello, do you have any more thoughts on Sparda and Mundus you wanna share? ππΏ
AAAAH, finally someone asked me about this YES, I do.
With how devoted Sparda once was to Mundus, winning him the throne of hell, I imagine they were close quite a bit. I see them as childhood friends, with Mundus being slightly older who guided and kinda showed him the way.
Since Sparda is often associated with swords (even his name is interpreted as a word play on "spada" Latin word for sword), I see it as Mundus put the notion in Sparda's head that he is a sword, a weapon to be held by Mundus himself. Both as a way to have this uber powerful demon by his side and...well Mundus kinda came to Sparda. As much as someone like him can.
It wasn't healthy but Sparda was..."happy". After all, Mundus is all he's known. Berial describes Sparda as "cold and quiet" but Mundus had seen his softer side.
Also Mundus was a little jealous when Sparda connected with others like when he took Baul and Modeus under his wings. They were just his apprentices but Mundus just didn't like someone else taking Sparda's time and attention but he let it slide because the brothers made Sparda happy.
But when someone like Nevan flirted with Sparsa...Mundus saw red. He sabotaged it bad.
Sparda is clueless the whole time.π
