Jenna's condition began to stabilize, only still needing a few days of recovery. While waiting for the results of the test of both parents, to determine whether it matches his marrow. Tara and Billy deliberately didn't tell Jenna this, they were sure that the girl would not agree.
Blake also understands how Jenna's character is so well that it doesn't say anything about donors. He will only do what he is capable of doing. No more wasting the opportunities.
He planned to tell about his feelings for the girl, without delaying anymore. However, of course, it will be done after Jenna recovers. Otherwise, Jenna would think Blake said that just out of pity for her.
Blake accompanied Jenna all day until the girl repeatedly asked how she worked. The man just replied with a smile, not wanting the girl to think too much about things that could have caused an argument.
He just wants to spend more time with Jenna.
