There's bonding there with the whole "famous parents" thing though idk how Cricket feels about having pretty Big Deal parents (as opposed to Iris who's like NOPE about it all the time)? Either way, Iris will be friendly and may have talked a little bit about her dad, at least assuming Cricket didn't have any presuppositions when she asked. And she probably would've been more willing to talk about things like "he's a total sell-out because he supports Tutshill" and "he snores so bad sometimes that Mum makes him sleep in his office" which is not helpful for Cricket's thesis, but yanno.
