If you say so. :P

It's where the frog is.
Of course, an SG method would be useless for a warpless run, I'm just doing a VK route for fun. :)
So far, it's basically identical to the HC route up to getting HC, lol. All for Magical Tickets. Afterwards, I get Cream Pie from City of Haze, SG into the dark portrait room from Keremet's save, and get Owl Morph from Dark Academy (whose portrait isn't locked for some reason). Then it's either Forgotten City to master Cream Pie off of Laura (probably worth getting Master Rings if you do this) and maybe get Griffon Wing for added mobility for Drac, or go straight for Sanctuary, Sisters and Whip's Memory.
Anyway, the point is that there might be a TAS way to glitch yourself into the gap without morphing and SGing. Maybe try jump kicks or char-switch-skidding similar to how you can Speed Up-slide into the CoH entry gap without Lizard Tail - which may also be possible without Speed Up.
