Melancholicky

Lena and Martin announce to the kids that Lisa Apple's baby, Annie, is their half-sister, and Martin is surprised when they aren't interested in meeting her. Lena feels the burden of being stuck in the middle between Martin and Lisa but still offers to help bring both families together. Meanwhile, Mason overhears Lena and Martin's conversation about Lisa's financial difficulties and decides to start a fundraising campaign to help. Elsewhere, Lena feels a bit of empty nest syndrome.

Lena und Martin haben beschlossen, den Kindern gegenüber Farbe zu bekennen. Mit etwas Herzklopfen erklären sie ihren Sprösslingen, dass Annie ihre Halbschwester ist. Kaum lernen die drei ihr neues Geschwisterchen kennen, droht es ihnen jedoch schon wieder abhanden zu kommen. Vor allem Mason ist völlig verzweifelt. Er hat sich auf der Stelle in seine kleine Schwester verliebt.

Lena e Martin dicono ai figli che la piccola Annie è la loro sorellastra. Lena cerca di riunire le due famiglie, mentre Mason avvia una raccolta fondi per aiutare Lisa.
