It's clearly depicted in an ending where Durge breaks up with him, where as spawn he's fearful and holds a knife behind his back when talking to Durge, while as Ascendant he is perfectly calm and knows he'd immediately destroy them if they tried anything funny.
What's this now? Never saw the knife one.
It's there around the 0:40 and 1:00 minute mark.
That is so Astarion though. Always ready to knife someone with the excuse of "it had to be done".
Also that "people can be quite meek after seeing you murder their former master." He's such a dick, I love it.

That sounds like Gale took him to a library and he was bored.
