Penny consulted her text book again looking for the characteristics of 2 and 8, making note of them on her parchment..
Text Cut: characteristics
2: Harmony, unity, relationships, collaboration, duality, humans/human magic
8: Authority, finances, business, success, material wealth, self-mastery, complex thought/reasoning, fluidity, movement
Penny thought about number 2 first - it contained Harmony, human/human magic .... then about number 8 which contained complex thought and reasoning, Authority and movement..
Then she had a thought - it was probably wrong, but it was worth a shot.. She put her hand in the air..
"Professor, looking at both characteristics... I think maybe the 28 part of the series of numbers suggest mind power effects the curse which hold the basis of the box - One needs to be of strong mind and of course magical, but then they must have thought and reasoning with Authority in order to break the curse on the box!", lowering her hand again...
She knew she was wrong - but she had to try.
