When saying goodbye to Sarah, Carina says in Swedish "jag kommer att sakna dig kompis," which means "I'm going to miss you, pal." Sarah answers in Polish "stesknie sie za toba tez", which means "I'll miss you, too". (The Polish bears some light English accent, but is nearly flawless overall, thanks to Yvonne Strahovski's growing up as an English-Polish bilingual.)
Morgan says that Carina is "just some girl" but a Swedish supermodel, which is exactly what she is in real life.
Morgan's full name is revealed to be Morgan Guillermo Grimes.
