“I think actually being involved with The Dark One would grate on Toph, and I can’t imagine her messing around with him for any reason except trying for a baby. But Huan’s face, physique, and demeanor imply that Grandma may have made just such a calculated move.
However, here are some other factors to take into account: First, the apparent resemblance to The Dark One could actually be a resemblance to Baatar (who’s similarly tall, lean, and saturnine-looking). Secondly, if one had to imagine the hypothetical daughter of Toph and Haru with a strong family resemblance to Daddy, the result would probably look eerily like Su. ”
I can’t imagine the dark one with toph too! Their characters don’t matched.. unless the dark one composed some poems about toph and won her heart.
I thought toph and satoru from the rift are a good couple. Damn this episode sunk my ship before it can set sail. Now I hope that the 2 fathers do not belonged to any characters which we know of.
