Yes,indeed Amy - I had the same recollection about Bolle's early departure last year. I'm sorry to say it left me with a bad impression of him and wondering about his commitment to ABT. After all Gomes and Hallberg can't be expected to cover all of these kinds of absences without risking injury to themselves.
Yes, I think this is the part that bugs me. Gomes and Hallberg end up doing the heavy lifting in these situations because it's hard to replace someone with the "starpower" of Stiefel with say...Hammoudi or Radetsky or any other number of the guys who should be getting chances at stuff like this with the exit of many of ABT's men (especially when Stiefel was due to partner some of the flashy guests this season--I doubt Cojocaru is popping over to partner a corps dancer in his debut). Gomes and Hallberg are the safe choices...they are tall, popular, excellent, dance the whole rep and partner a number of the women well, but it puts an unfair burden on them when these hasty, weird exits occur.
What abatt noted about Corella seems absolutely true in this case, unfortunately. (Also the part about poor Stella, it's just cruel)
