hmmmm.... is the bend of time even accessible at that time?

if not, then keep going through the game until it is accessible.

if it is accessible, talk to the lil blob guy at the end of time, you might have to talk to him a couple of times.
(btw, after you get janus by beating her in the Grand Slam, have janus talk to the blob guy and he'll give her her lvl 7 tech)
