Oh I definitely agree. He's got to be aware that their ultimate goals most likely are going to lead to something bad, especially after this little escapade. I'm sure he's thinking that imprisonment will be the worst. Poor Chuck!

Not sure if Ellie's completely aware of the state of Chuck/Sarah. If nothing else, she seems completely at ease with Sarah. She either has no idea that they're no longer together or she's aware that their breakup was fairly amicable.
