It's only been a few days since the moon warp, so it hasn't been too long with things uncertain, but Jack is also unhappy with things being uncertain. So having Serph hovering, clearly wanting to say something, he thinks might be a good step? Maybe? Unless he wants to say something bad. Jack waits, trying hard not to fill the silence with words like he usually does. It's very hard not to just say "out with it".

So he's got his hands busy and his eyes looking at Serph sidelong when Serph finally asks, ears perking up from their skewed angle to something that perhaps looks hopeful. He puts the mending down and looks at him more fully. "We can always talk, Serph. I will always want to listen to what you have to say." Even if it's "we shouldn't sleep together anymore" or "I want John not you". He can take both of them if he must.
