What I’ve been thinking about is Meulin and Kankri. Meulin as a Mage of Heart was a great Matchmaker, but that doesn’t fit with the introspective nature. But Kankri, a Seer of Blood, could see his life on Beforus as the Signless, but wouldn’t Blood, about comradery, be more of a matchmaker? Heart always felt like it would be more fit for Kankri’s abilities and Blood, Meulin’s. Though, that wouldn’t fit with the trolls sharing aspects because they share signs.

It does make sense though! Meulin just Knows what pairings will work together, she has a sixth sense for relationship stuff, and uses her powers selfishly to fulfil her Ships. The Signless, on the other hand, had Visions, seeing his Pre-Scratch life- This works on multiple levels. He saw the way the Hemospectrum worked on Beforus, the less violent Unity, and saw through his own Bloodline in a way, experiencing the events another version of himself experienced to, was attached to.
