There is a blue painted wall. ... One day, you saw some buckets filled with magenta color: ... "Oh no, please do not paint this wall with this color.". He is bad, i do not like this color, ...
... ups ... I ment "IT is bad" ... i do not speak about the guy here ...
A few days later, the wall is still blue: ... "Thanks god, he has made the right decision and returned the color."
... but ...
We still do not know what happend. He, she(!) or even them(!), could have
Painted the wall with cyan and used the mangenta to get the correct blue tone
Used the color for a different place
Put the color back to the storage room where it is lying pointless around for ages and is worn out only to clean up this damned room monthly ... :)
...
It could be anything and we have no prove of anything. ... Not even a good indication. ... If Dima and Rebecca are gone when the apartment get back online we have no prove for anything.
He could still be back hours later (or even days); he could have arranges the departure a long time ago (may even use the same plane as rebecca ... ); ..... so many possibilities
Beside the photos he took, he did nothing wrong so far. The girls seems to like him. Some even were intimate with him. ....
I suspect, you want to dislike this guy, but you should at least try to be unprejudiced. ... Not all guys are bad. ... He may be one you would like if you know him in person.
