Gohan does NOT need to lose to take his training serious enough.
He already wants to get stronger to protect his loved ones.
He has resumed training with Piccolo.
When Gohan jumped into the ring previous episode, he was eager to show to his father, how strong he is right now.
He is already making effort to get stronger again.
If he needs to do this even more, barely winning against Lavenda will give this result as well.
As it will show him that where he is, might not be enough next time.
He will realise he needs to be better prepared next time and therefore will increase his training.
It will be a ''damm that was a close call, I need to increase the lvl of my training more'' type of wake up call.
Besides Whis is also watching. Who may want to train Gohan too.
Regardless of if Gohan wins or loses.
I dont want Gohan to lose after waiting so long to see Gohan in a serious fight again.
We also dont know if this pretournament will be over if uni7 has won 2 out of 3.
As the matches are to entertain Zeno.
The third match Goku vs Bergamo could just as well start with Uni7 having 2 out of 3 due to Buu and Gohan winning.
Meaning Gohan and Buu winning does not have to be an issue.
As some people say Gohan needs to lose for it to be 1-1, making Goku vs Bergamo the tiebreaker,
however a tiebreaker is maybe not relevant for these pretournament matches.
Just make Uni 7 win 3-0. If one of the uni 7 fighters has to lose I rather see Goku lose one due to some surprise ability and have Gohan and Buu win theirs tbh.
We will probably see Goku shine enough in the future episodes.
It might also be interesting to see Zeno's reaction to Goku losing.
You are a true DB fan, You sound like a buddy of mine!
RESPECT..
But think about it like this!..
Gohan has been out of the loop for awhile when it comes to protecting the earth an family.. (He's left it to the pure bloods.. Goku/Vegeta)
Him losing would put more intrest on his character.. It wouldn't be fair if for after 15 years or so he hasn't fought to the death or even a serious fight since Cell then he wins a bout were his opponent is going all out.. (He's rusty in real combat)
Gohan is not the fighter he used to be an losing would build on his character even more.. The reailization of losing his love ones would (Even if it's just a spar when he knows what could happen if he loses the real tournament) push him to become stronger. (Angel Whis Training)
This could leave us with more episodes to see him train with Whis.. (if there is rest time after the preliminary rounds)
