See it's ironic because usually people who come back from the future do so to prevent a horrible thing from happening but in this case it's me who needs to do that because it looks like she's been doing lots of meth.
Except she's from the future, so I don't actually need to time travel, I just need to wait until she's born and then one day pull her aside and be like "Time traveling hit and run isn't normal, but on meth it is"
