I just love ellie - the way despite being a regular person, she saved her brother, a spy from a big secret organisation just because she is an elder sister...
I just love the brother-sister relationship

Ellie should have been allowed in on the secret by the end of season 3.  It would have allowed her to be part of more of the integral stories of the show.  What a missed opportunity!

Give Ellie knowledge to match Chuck, and time for both of 'em to get their game together, and I have a hunch Chuck and Ellie together could take on just about anybody in the game and win.

Love Chuck and Ellie

Seem like Chuck is the big brother and Ellie the little sis

@TheEliseSuzanne nah the sister causes most of the trouble with her whining
