This is pretty normal old dog / puppy behavior.
I'd make sure the new pup cannot bother her in the evenings. Its just not going to go well to have the young boy bothering Grandma when she's tired. Keep them physically separated, but make sure that does not mean grandma is in the back room. Put the pup on a leash or on the other side of a gate, or in a large crate in the living room with you. Puppy is probably tired by then too, and won't have any self control, so its a good time to contain him anyway.
Things will probably get a bit tougher before they get easier. The teenage months are even harder for old dogs to take, but just keep working with the pup to teach him other things to do when he want so play with the old lady. We've often taught the young puppy to pick up a stick to play with when he gets rambunctious outside with the older dog. Enough repetition and its pretty easy to re-direct the puppy to another activity that you will engage with him.
Management, management, management. No one needs a scolding. Just stay calm yourself, and be empathetic with the old girl, and patient with the new pup. It will all be OK in the long run. By the time he is an adult they will be on more even ground and are likely to just be good friends.
