After a near thing with Mimic's infiltration into HQ, Whisper reflects on everything and decides to go for broke. Better to love and lose than to never love at all. Tangle gets a shock to her system when the wolf takes off the mask and pulls her in for a "word."
While SEGA may not approve of full on kissing or explicit heart bubbling, I can see IDW getting crafty with heavy implication. Having the mask block their lips. The Yuri On Ice method (#Justice4IceAdolescence).
I mean, they did sneak the colors of the Lesbian Pride Flag for the pair. They're crafty, they are.
