will/(be) going to

What’s the difference between using “will” and “going to” here?

Steve:Jackie, are you ready? We want to be there on time.

Jackie: Nearly, but I’ve still got to dry my hair and put my make up on.

Steve: OK, listen, we’ll/we’re going to walk down the road and you catch us up. OK?

I refer you to the summary at the end of this thread.

Thanks for that, but I’m not sure it fits the above too well. Any of your own thoughts on the question would be useful.

On the contrary. It contains excellent advice. Read, consider, and make it your own.

To me, it doesn’t apply easily to the thread examples. Does it to you?
