I thought of something they could do was while Kenobi is off planet, he could use the force on Biggs to be a protector for young Luke, since he’s a little older than Luke. I’m sure Biggs can take care of himself, and Kenobi realizes that’s his best bet.

Unfortunately, this isn’t going to happen. We could probably see him make an appearance, but nothing more than that.

It’s more about Anakin and hunting down the remaining Jedi with the help of inquisitors. Also from the rumors Leia will also make an appearance, I’m sure Bail Organa is going to be around somewhere.
