Ask yourself this, what did the references add?
Did they move the plot forward? Did they introduce anything new?
All they did was let us know that the things Jack did in the past had an impact. We could have guessed that without having to waste 10 minutes of a 20 minute episode on it.
References aren't bad, but they shouldn't be held up like, "Hey look at this? You remember this don't you? Good goy!"
These were cheap methods of baiting nostalgia and winning people over on Ashi, even though it was all undeserved to her.
