Well
Krillan is afraid that Trunks has gone psycho because
of the way he looks (like an ultra super Saiyan).
Because of this Krillan gets scared, but when Trunks
tells him to go and take Vegeta to the Kame House
Krillan realizes that Trunks "didn't go ape like
Gohan." Trunks also hands Krillan a senzu
bean for Vegeta. Krillan asks if Trunks would
need it and Trunks said that he didn't plan on
loosing. In the hyperbolical time chamber Goku
tells Gohan to try and catch him for training.
Gohan does a very good job blasting at Goku, but Goku
keeps dodging the attacks and the time chamber gets
pretty busted up. When Gohan catches Goku, Goku
says that they should clean up the mess and then take
a break and eat. Back at the battle field Trunks
shows Cell his true strength and becomes Krillan
thinks that Trunks is the strongest warrior in the
universe. Trunks signals to get away with Vegeta
and that's exactly what he does, but Cell somehow
found out about their secret plan to get rid of Vegeta
and he didn't even care. Yeah another pretty
much pointless episode.
