Reactivating Colette question

[Count Domar]

When I do the 0 AP action to reactivate Colette does she reactivate immediately after she finishes her first activation or does it mean that I can reactivate her again after my opponent has at least activated one of his/her models?

After your opponent activates a model.

[Finnegan]

She has to finish her activation (and any companion chain she is in) then your opponent can activate a model (if he has any left) then she can reactivate - or you can, if you want, have her reactivate later, she doesn't have to do it right now.
