In S1E4 ("Wrath of Con") of Veronica Mars, a memorial fountain is dedicated to Lilly Kane. Logan, her ex-boyfriend, is assigned the task of creating a video montage as a tribute to be viewed during the ceremony.
The video itself pulls largely from events of the characters in their teenage years, but the video begins with shots of Lilly as a child. There is one specific shot that is clearly Amanda Seyfried as a child, but what about the rest?
