YES ! Finally someone ( or somepony, I'm not sure ) notices this ! The time-travel episode made no sense ! The only reason Twilight became future Twilight was because future Twilight travelled to the past and got her upset, in other words she's the result of something that she's the cause of, it doesn't add up !!

And so once again, doctor Whooves has to set out to fix things. Way to go Twi, you got your dimention destroyed. Of all the ponies in town, really...*sigh*
