Hi,
Saturn/Shani-dev’s Maha-Dasha for your brother does not start until March 2025. There is some time for that… not to mention the fact that it lasts for a longer duration (as per Vimsottari Dasha system) and will invariably be a mixed bag with ups and downs.
In your brother’s case, it looks like the theme is going to be centered more around family, children, friends, health and invariably have some impact on work-place, career etc.
That said, I’d like to remind of what is said about “ignorance being bliss”. So, too much of persistence in wanting to know everything about future may not always be good.
Take care…
