That was Arabella Sear-Watkins, not Alexa Severn (their names are a bit similar!). Arabella had a groin injury from a fall during one of the practice sessions at JGP Istanbul. I had a look the other day, and cannot see any sign of her having competed since. The GB senior qualifier she competed in was earlier.
Alexa completed both programmes at both of her JGP events. She was under-prepared for her first one because she replaced Daria Dalgich (who was injured) and only had a couple of days notice but, as far as I know, Alexa wasn't injured during either of her JGP events.
