So I'm not sure if it was spotted before or not, but the last Dream Homura had, only a few updates ago, that very much reminded me of how a Witch and her Familiars might act.
Another interesting point in that scene was it was a (what we think probably are) Homura copy that went through a fracture/portal and got shit-stomped. We've previously established that at least some of these are locked away memories, but I'm wondering if it might also be more directly linked to the fractured state of the World. That is that the Homura who got cut in half and Prima was healing might have been the one exploring SAO, where we also got bisected, though I'm not sure how exactly, so... Also the mention of "She" makes me think it could be a memory, but I don't know who cut us in half in SAO, so that could be a she as well.
Also, re-reading the Waver Velvet omake made me think of Great Father Teacher Waver Velvet for some reason.
Waver: *Dripping in a green fluid placidly* "And that is why you always double-check you're summoning circles to make sure nothing is out of place and/or inside them."
"SKREEE!" *Giant bug monster jumps up behind him before exploding and covering Waver in more bug guts*
Waver: *Nods* "Thank you Ms. Vencia for showing the importance of double-tapping as well. Class is dismissed."
*Half the students, the greenhorns, shakily make their way out while the other half, the veterans, calmly walk out*
