Exactly. For what we know, the junior could have actively complained to the manager (wrongly or rightly) about her mentoring. OTOH the junior dev might have appreciated it. We can't say for sure.
Some people (myself included) prefer to get a general direction and then later to come back for further questions. Too much information in a short amount of time can be overwhelming, I need some time to absorb and read it up in the internet. A few keywords might be good enough to get someone going and figure it out themselves.
"learn at her own pace, without any pressure from you." This really sounds as if the manager had the junior dev's best interest in mind. I don't see how the manager said this to get back at Caroline, as was kind of implied in the article.
