Strewth Jazz, you managed to delay your first sting a while. Sounds like your handling technique is pretty spot on.
Why not phone owner of trampoline and ask if any bees remain in situ? If a small amount of bees with queen remain, they usually stay put as they sort of lose heart somewhat.
My guess is that they are just fine and will come into visible lay once you have enough drawn comb. I usually drop in frame of already drawn comb if I have it to ump start the queen. Having said that, the last cast I collected (favour to householder) was small and no laying queen became evident. There were also some evidence of virus present.
A frame of eggs and brood never does any harm anyway, even if they do raise emergency cells you could still knock them back and try introducing your mini nuc queen.
You might as well attempt the full General husbandry syllabus in your first year...
