A college graduate was left stunned when her sister returned from U.S. Navy duty in Japan to photobomb her graduation photo with family. Lexi Gette, who studied at Temple University in Philadelphia, is extremely close with sister Gabby, a lieutenant in Sasebo, Japan, and dentist on the USS America (LHA6). Gabby, 29, only gets a limited amount of leave, so Lexi was left upset when she was faced with the prospect of her sister not being able to attend her graduation on May 9. Lexi's graduation had extra significance to Gabby, too, as she graduated with a bachelor's degree in biology, which she plans to use to attend dental school and become a dentist in the Navy like her sister. Secretly, though, Gabby had spent some time planning her next trip back to the U.S., which she made sure would tie in with Lexi's big day. Having watched the graduation ceremony away from her family at the top of the venue, so Lexi wouldn't see her, Gabby then made her way to the part of the campus where families were having their photos taken. With her uncle's cellphone capturing her entrance on video, Gabby snuck into a family snap that Lexi was having on a set of steps with her parents.
