The sight of you flirting like 
that while you research...
...رؤيتكما تتغازلان هكذا بينما تقومان ببحثكما
Wie ihr bei der Forschung flirtet …
Transmitiré al mundo su imagen
coqueteando mientras investigan
Transmitiré al mundo
vuestro amor mientras investigáis,
Cette romance
qui s’entremêle à vos recherches…
Lo spettacolo di voi due che flirtate in quel modo
mentre portate avanti la ricerca...
Quero retratar os dois flertando
enquanto conduzem sua pesquisa,
Ваш флирт в процессе научного 
исследования...
