Hello and welcome. Yes the weather here in CA is certainly better than BC...
Do the two of them live in the same enclosure?
What you have in the pictures there is tortoise aggression. They are not hanging out. The one is getting in the face of the other as if to say, "HEY! Get out of my territory." The head resting is the same thing. The dominant one doesn't understand why the submissive one is not taking the hint and leaving. The submissive one would like to leave, but can't due to confinement.
There does not have to be obvious ramming and biting for this to be a problem. Just the sight of the other tortoise across the cage can be a stressor. Chronic stress of the nature that your tortoises are currently enduring can cause a weakening of the immune system and lead to them succumbing to sickness. Eventually this is going to escalate. One will likely get sick and begin to withdraw and try to hide more and more. You may come home one day to find a missing eye or leg scales. Its just not worth the risk. They don't want or need company. They can get along in groups in large enclosures sometimes, but even that doesn't always work. Pairs almost never work.
Tortoises should not be housed in pairs. Especially not russians, which are probably the scrappiest species out there. Check these out:
