Ralf was quick to interject as he explained the accident was caused by the actress attempting to do a star jump in the sand on the beach.
“I feel I should say,” he remarked. “Nobody told you to do it, by the way, it was entirely by choice.”
The actor continued: “I remember it happening. We all ran onto the beach and Shyko decided to do a star jump and land on the sand. The first four times was great but the fifth time was a disaster.”
Shyko added: “I basically tore my calf muscle. But it’s very Ruby-esque and you’ve got to get into character.”
