Don't know exactly what you're asking, but ill take a stab at it and talk about jBB stuff and Bento follow ups.
If you're talkin about her post jBB ender... there is alot of stages to look out for.
At the first bounce, I tend to see if they will tech either forward, backward, netural, or just bounce.
- Forward teching usually means they wanna get in and try to get in close to hit me. Forward tech is also slow and can be reacted to with a meaty 2b or mash out the 2As...
- Netural teching prolly means they just wanna get up quickly as possible. In the corner, the 5A/2C option select may work (I dont use it much...). Further jBB's means that they will prolly forward tech again and i can react accordingly.
- Back teching can mean they just wanna get the hell away from me. I'll then choose if i wanna chase em down or just throw a pot at em.. or continue netural spacing
If they don't tech and just bounce...
- prolly the best ender is a 2C>623A>22A/B bento if you can catch em.
- An alternate follow up is to just jump up and add a bit more damage with another jBB or a throw ender.
- If they are too far, however, I'll just chase em down and try to react to a 2nd landing tech punish. Then ill just react if they faceplant to the ground or hop up (Tech). I'll react then.
If it is post bento mix ups you're lookin for... I'll just say get the timing of the bento explosion in your brain and get used to the proximity that it'll explode. When the opponent recovers completely, they only have umm... 1/2 a second (?) to react to the bento, so they gotta act quickly...
If the opponent...
Blocks: Throw or blockstring pressure.. or go for her 6B(B) overhead... or 6C ,Delayed 2C.
Jumps: Meet em in the air or go for a guard break (dash in A's can do the trick) Even 623B will do nicely.
Backdashes: Ya can prolly chase em down.. or if they always choose to back dash, use 22B instead of 22a. Let them backdash into a bento.
Shield or Bunker: Risky move, but it may work... Just be weary of trying to go for Meaty hits. You can prolly go for a 5B to counter low Shield or 2B to counter high shield... or laugh at the opponent shielding to nothing and punish em.
Mashes: Meaty... maybe? or just block. Let them risk getting blown by the bento (muwahaha)
DP's: Honestly... i hate these... just approach em cautiously... 623C at a safe distance... or block and punish em according.. Heck.. even a pot works at em.
Dodges: Actually a fairly good option for the opponent... You can throw em... or meaty 2B em... Also use 5(C) sparingly overall.. cuz good players will dodge it at the right time and punish ya.
EX Hiero/Hime 2369C/Any good wake up super: Just be weary and be ready to block... or shield... or cry if you're hit.
These are just some of the things that ya can do. Hope this gives overall insight with this crazy maid.
Edit: In addition, there is absolutely nothing wrong with just doing nothing and seeing what the opponent'll do in that moment they have to react to the bento. Who knows' it may give you some insight later during the match. Also... throws are awsome. Learn ways to tick throw with her. She has one of the best post throw in the game being that it gives you like 2 seconds to setup whatever the hell you want.
