The last card is The Hierophant, which represents wisdom and awareness. This suggests that despite your uncertainties and worries, you have the ability to make an educated decision about the current situation. While you may feel some fear or concern, you do have a sense of responsibility and obligation towards your old flame, and this may prompt you to act with caution.

In conclusion, the cards suggest that you are currently torn between two different directions: on the one hand you would like to give your old flame a second chance, but on the other hand you fear the risk it would entail. However, you also have the skills to make an informed decision about the current situation. Therefore, the most likely answer to the question "Should I give an old flame a second chance?" would be "Yes" - with caution.
