1FLAMEN6rq2BqMnkUmsJBqCGWdwgVKcegd is a vanity address. Using a word list is impossible.
She got a random private key similar to this - 5KTVSQgC3Mx1hBWzFSADwYds4L31nbPSNPRQwE1F2GwDfdUjSZK
I found the vanity address 1FLAMEuWQftZ6moQvbAZo5aTqpPbeCrjZj the above is the private key.
She then encrypted the key using BIP38 and got something similar to this.

This is what is hidden in the flames. Find 6PR and you get the BTC.
It could be in binary in which case you are looking for this string 00110110 01010000 01010010
Hex is 36 50 52. I don't think it is encoded using hex though.
It could be an Base 64 matrix in which case it could be random. You can't brute force that.
