She, when she heard [that], rises up quickly and comes to him.

John 11:30 Now Jesus had not yet come into the village, but was in the place where Martha came to meet him.
John 11:31 The Jews therefore who were with her in the house and consoling her, seeing Mary that she rose up quickly and went out, followed her, saying, She goes to the tomb, that she may weep there.
The verse centers on "heard", "rises", "quickly", and "comes". It is saying that the verse draws attention to "heard" and "rises", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 28's "And having said this she went away..." into verse 30's "Now Jesus had not yet come into...", so "heard" and "rises" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "heard" and "rises" with trust shaped by these words, not by a vague optimism outside the passage.
