"Of course I don't think you should not date," Jack said and then stopped because he had to think that over to see if it made any sense at all. Which it really didn't, quite. Oh well. He continued on. "I think you should date but only if the person is perfect for you and will treat you the way you deserve!" And for whatever reason, in his mind, Frank was NOT that person.
"Frank is... well, where to begin!" he huffed, because he couldn't exactly start pointing out all of Frank's flaws. Given that... he didn't actually know Frank at all. Minus the very brief meeting of him in the cafe, and the only real problem there was that he had called Andrew 'pet'. And yet, Jack was positive that he didn't like him.
