With Shadows of Valentia potentially improving on and/or expanding on Gaiden, it had me thinking about supports.
By no means are supports confirmed or disconfirmed, as we have little information to go off of, but I imagine most of the community interested in SoV would like some sort of support system to be introduced, in order to give the characters more/better characterization and development.
This got me wondering, what characters from Gaiden's original cast could have plausible, interesting supports with each other?
For the sake of consistency, let's assume a C-A support system similar to GBA and PoR Fire Emblem, without marriage but with potential for paired endings.
I'll start with some obvious ones:
Alm and Celica: This support could highlight their different opinions and attitudes on war and conflict, and further develop their relationship with each other. However, issues with the support could come from the fact that they are together only very briefly in Gaiden.
Whitewings with each other: They are sisters. I'm sure IS could make something work.
Zeke and Teeta/ Cleive and Matilda/ Clair and Gray: All canon pairings from Gaiden, but said characters had very limited interactions, due to Gaiden's small script.
I have plenty more ideas, but I'd like to hear what others think first.
