I wrote down some ideas for "Glacier Surge", lemme lay them on y'all.
Glacier kisses Blaze in front of everyone, and the nature of the kiss is unambiguously romantic.
Glacier starts to refer to Winter as her son.
Glacier drinks with the common Icewings
Glacier is relieved that Crystal now has a partner (Gharial), as this means Icewing nobles will stop trying to get her to set Crystal up with the sons of the nobles. Alas, She still has to deal with this for Snowfall and Mink, but by the time they are adults, it should be clear to everyone that Glaciers daughters are not on offer.
